The F-80C is really good imo.
Looks like your already on a good path, F3H is pretty decent
First hand experience with Canberra mk2 (which is what the B-57s are) are fairly decent for base bombing, can usually get too a base just fine and quite often back to base (youd be surprised how fun they can be to dogfight in, at least the ones with guns) not rank 6 but perfectly usable for grinding most rank 6
But the F3H-2 is very strong for the BR, probably should be 9.3
F-104s can also be annoying to deal with and very strong in the right players hand
f-80c is crazy strong, one of the best dogfighters at that br
I’d use the F2H-2, a very nice plane and one of my favourite early jets
