Using a larger preflop raise to target players that call too wide is reasonable. But when using a 5x sizing, I would prefer either to have a stronger hand (QQ+) from early position or only do this in later position (HJ or later) holding JJ.
The 3bet squeeze from SB is really strong. Given your raise size (5x), position (UTG+1), stack depth (100BB), and a caller, if SB is a reasonable player you can expect them to have a strong hand to raise here. Facing this strong of a range, I prefer a call over a jam.
Given the flop, you may be getting in stacks anyway, but flat-calling allows you to get value from any weaker hands that SB may continue firing with.
