open 82%. call bb 90%(basically fold 83o-, 72o, 62o, 52o, 42o, 32o)
3 bet/call bb margin is near these hands: A8s/A7s(vs players that fold a lot postflop i throw in A5s-) K9s/K8s, Q9s/Q8s, J9s/J8s, T9s/T8s, 98s/97s, 87s(this one is either yes or no depending on opp went to showdown frequency). A9o/A8o, KTo/K9o(i think gto 3 bets K9o at low frequency but havent studied charts in a while) QJo/QTo. and pocket pairs somewhere between 44/66.
flops like 456r, Q54 mono, i expect many flop checks by button so i donk here often(relatively often maybe 15-25% with strong hands and draws). but if they dont flop check much i'll check 100% here and check raise often.
flops like 554, A72, K22, i check 100% in bb.
conversely, drawy flops i check in position a lot, dry flops i bet at or near 100%.
on flop in bb, youre getting 5.5:1 to continue(about 15% pot investment) and u need to consider opponent turn bet frequency(u cant chase really weak draws vs opponents that bet a lot relative to gto because they will deny your river equity, but u can chase very weak draws vs players that check turn often because you get to realize much equity on river often for free). top pair is 100% check raise in bb with rare exception(either slowplaying to raise turn, or hoping to catch bluffs vs very tight bettors when my kicker sucks) middle pair is really strong on some boards but not so much on others. do some equilab work for this part on your own. its too complicated for me to explain in few paragraphs. otherwise any pair or real draw(to straight or flush including weak gutshots) can profitably call flop, and even weaker draws can call the flop on some boards(six outs to strong second pair with backdoor straight/flush potential is often a call). u gotta consider the average price to see the river. passive opponents let u call flop wider and aggros make u fold flop more. also ace/king high is folded on flop at low freuqency depending on board. queen high can call lots of boards but should be folded more often than A or K high.

4) use some sort of polarized 3-bet range preflop? Is polarized ranges even a thing in limit?
polarized is a fun word that gets thrown around a lot, however if u think in terms of profitability you will realize that theres actually linear progression from (fold = 0ev avoiding negative ev calls), (call = slightly profitable), (3 bet = very profitable) notice that in order for 3 betting to be correct it must have higher ev than calling of course. so in terms of polarization(you see gap between strong hands and drawing hands on equilab grid) theres not much happening in limit holdem(we dont see much gap like in no limit). also nobody ever folds pre vs 3 bet(at least nobody decent does), so if 87s is a 3 bet vs this opponent, then surely 98s, JTs, and all stronger suited connectors are 3 bets. the only hands that violate this principle are the Axs wheel draws, which are stronger than A7s and A6s thanks to the added draw value.

5) admit defeat, not play HU and accept that I won't be able to get a game going?
depends on your motivations and goals. this is entirely up to u.
