4way without info there is no value in betting this flop imo.
could argue about protecting our equity (your sizing is fine for that purpose) but i think it's just too likely that one of them has "something" and your hand has almost no potential to improve.
when we are called i'd just give up. even 7x improved so we can't really get value from enough worse hands.
as played river shove seems fine.

he looks bad so Jx may call, he'd probably donk with his value range (7x+) but he could have these hands too.
worse hands Jx, 7x, 22, T9, better hands are JJ and 77
