The first two hands are okay. Another option is to underbet the pot trying to represent a draw, then 3-bet your opponent all-in if they raise.

Yet another possibility is to just call the flop and then min-raise the turn if a safe card falls. If your opponents are paying attention, it's important that you play big draws exactly the same as sets.

In the second hand, I would personally 3-bet preflop for a few reasons. You may be ahead at that point, your opponent is unlikely to shove over your 3-bet, and you can c-bet the flop and take it down unless your opponent hits a big hand. Finally 3-betting medium or better pairs form the blinds will make it much easier to stack a TPTK hand.
