1) you don't want to introduce bunch of names from std into client's scope, can cause all kind of nasty problems for users. C++ name lookup is complex as it is.
2) if I got a pointer to MemoryPool and tried to delete the referenced object, I would invoke undefined behavior, even thought virtual methods are strongly suggesting me that I should be able to do it
Some more points, since you said C++ is love:
4) virtual void* alloc(const size_t size)=0; - const is needless
5) if(!TCapacity) will give you a warning (on /W4 maybe) if TCapacity is 0, but
6) the bigger problem is uint8_t m_heap[TCapacity], since zero-sized arrays is not standard C++
So I would either go with static_assert and ensure that 0 is not valid value or make specialization for that cas.

1&2 - see my edited post
4, i use const descriptively, even if it doesn't do anything, unless there's a reason I shouldn't
5, yeah that's a nasty habit of mine
6 I introduced a static_assert to fix that in my later code.

To whom this description is directed? Users of the interface don't not care about it. Implementer of the interface is free to leave it out when override the function, since compiler ignores const when doing overload resolution. It is just implementation thing leaking into syntax of function signature, but not really affecting it. You can keep it class implementing abstract function to prevent changes to the parameter in the function's body, but in the base class it just confusing.

And some more:
7) You invoke undefined behavior in ~DynamicMemoryPool by calling delete operator instead of delete[]
8) i guess capacity, used, next should be const-qualified

whoops, and yeah your probably right. i love const and i hate const because i always forget it.

9) you want to disable copy and move operations (constructor and assign operation) on StaticMemoryPool and copy operations on DynamicMemoryPool
10) ~StaticMemoryPool() {} don't provide user-defined special members functions if they are not really necessary and if you do have to define them because language rules deleted them, use = default to retain possible triviality of these operations
General rule is if you need to provide a single user-defined SMF, you need to provide them all. It was called rule-of-three, now it's known as rule-of-five.
Think about using clang-format and clang-tidy (they integrate well with VS these days).

Okay I am aware of the rule of five but I don't actually want copy and move operations to work, consequently, no move and copy operations. Currently if I try to do those things, I'm pretty sure it doesn't compile. What's wrong with that?

Are you sure it does not compile? Copy and move operations does not produce error
Rules for which SMFs get deleted by compiler and which remain defaulted are a bit complex, so that's why it's better to be explicit about it and = delete those that you don't want and = default those that you want to keep.
The second point is to always prefer = default over {} since you retain triviality which is actual concept. Trivial type are easier to handle, subject to more optimizations and can be used in wider range of situations. It something that you probably don't need for arena allocator, so in this case it would be about habit and consistency.

Now that you mention it I'm not sure. I guess I should be explicit.

Then that would be an actual garbage collector, which I'm trying to avoid. 
Actually what I'm doing is kind of clever.
I allow you to allocate a "MemoryPool" on the heap or the stack, and then allocate memory from that pool. It does not allow you to delete. However, all allocated segments are always contiguous and sequential, leading to a number of performance advantages. Instead of deleting single allocations you can freeAll() to reset/recycle the entire pool and invalidate the memory therein. It's actually quite nice for a lot of basic processing scenarios. it's just inefficient for mutable data where sizes can change - which it's not designed for.

That's what AAA games use (and maybe non-AAA too, I only know what DICE did, as I worked there) - arena allocators.
When a level starts, it allocates from its own "arena", and when the level is done, the arena is wiped.
Lessens the risk of memory leaks and gives full control and trackability of all allocations.

Sounds like you're in regression.

That would make 3 people in the club - though I usually prefer C to assembler, I like a good delve into the madness from time to time.

Ok, now give it a name that references literature, something like "Quixote Garbage Collector".
Then make a slogan that's inspired by LOTR, maybe "I am Gandalf the White and I've come to collect your garbage" or "There is no curse in Elvish, Entish, or the tongues of Men for this garbage collector."
Now live out your life as Facebook, Google, Microsoft or Apple buys you out for quintagazillions$$$ and share some with me

It doesn't really do garbage collection as such.
As an analogy imagine the garbage man came once a week and burned your house down. It's much more time and space efficient than taking out the trash.
You can't actually delete objects in my scheme, only allocate to pools. You can recycle entire pools though, manually, freeing (invalidating) all pointers (or objects) therein.
Doing it that way makes it fast fast fast and it works on constrained memory environments. Also it was easy to code.
