.243Win, absolutely ideal for anyone who's small or recoil shy.
7mm-08, for anyone who "wants" more than the 243 and doesn't mind more recoil. .308 is fine too.
No one ever needed more than the venerable .243 for deer hunting. It is absolutely ideal for smaller, younger and/or recoil shy hunters and, quite frankly, darn near ideal for everyone else too.
I really like the 7-08 but it's not needed. .243 is plenty enough.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
