I usually play 2/4, but here are my thoughts.

1- I think is bad, after you 3bet the UTG I think his range is calling you on the turn like 100%. You have no outs so you probably gonna have to bluff the river like always and that's no good vs his range. Your cb as you said should be bigger imo. On the river I think you get called by 89 if he seen you do it,unless he is playing like 12 tables, and only small FD fold the river since I think FD + Overs can raise before then a lot.

2- Bad thing about that one is that its blind vs blind and no one ever believes, and even more so if you are polarizing your range that much. Also the fact that he saw you losing a big pot earlier could make him think you are on tilt and desperate to win it back, giving him an excuse to call.

3- He just 3bet a ck/raise in a UTG raised multiway pot deep. I don't think you have fold equity and he is willing to go allin. I would usually just ck/call in that spot, Folding is probably best as played, if you call he is not always gonna pay you out if you hit this deep.

4- I would look for his UTG vpip the higher the better, If he is decent I think I like this one better specially because of his bet size, but probably I'm lead/raising in this spot.

I think that you need more info on the villains to pull off this kind of bluffs in these spots, if they ever saw you doing that before, no one will ever give you credit.
