very standard spot

This is a situation where i sometimes wonder wether to bet or check, so i'm curious to see what your betting range on the flop will be, or do you check your whole range?

Table with 6 regular tags, all running around 21/17, 100bb effective stacks. opens to 3.5x
MP opens to 3.5x, CO calls, button calls, you call in sb, BB call.

Flop: 4dTdKc

Say u called preflop with atc, what hands would you lead, and why?

If the flop was 27Jr how would this change?
