I believe that I should call SDL_Quit before my program

there a way to have SDL_Quit (and TTF_Quit) called after the GC
has completed shutting down on program exit?
No. GC cleanup happens after static destructors are run.
If not then it could make things very complex and messy to keep
track of these resources.
You really, really, really shouldn't be depending on class
destructors to free resources like that. There is no guarantee a
class destructor will ever be called and they are
non-deterministic, so you can never ensure they will be called in
a non-problematic sequence.
There are a number of alternatives here. The one I recommend is
to use structs to wrap your SDL resources. It's what I settled on
long ago and works well for me. Yes, you will have to take a
couple of extra steps to cover all your bases if you don't want
to manually release things, but it's possible to keep it simple
and avoid messiness.
