I am wondering what kind of hands should I bet picking to 3b in position so I dont become too exploitable 3 betting with too narrow range as I feel the better regs take note of my low 3b% and play more agressive on boards that seem bad for AAxx type hands?

I've done some research/thinking and i've come to conclusion adding hands like 89TJds seam best especialy since these hands don't play very well multiway because of non nut flush draw and I can comfortably get it in preflop vs AAxx type hands and be coinfliping.I also found that even a bit worse hands do quite well vs AAxx such as Q987ds as it has cca 40% equity preflop on average.
But I feel my 3b% is still too low with just those hands so I am looking for opinions should I be 3 betting hands like QKJ2ds in position vs tighter players? Also I've done some experimenting with 3b hands like KKA3 with nut flush draw but I feel that when I get 4 bet holding those i'm in quite a dicey spot as its AAxx type hand doing the 4 betting very often so I'm dominated, but on the other hand I have a quite strong hand so it feels folding is a waste so should I be even 3 betting such hands?
