I don't like ur logic for smooth calling pf, because the donk is not that likely to squeeze (unless you had a specific read), and imo 100bb is enough to get away if you think ur beat vs the 19/9 pre or post flop.

otherwise I think what you wrote is alright and mostly comes down to personal style, but what I think is:
I like leading the flop a little more than checking, since you can get more info (possibly) and similar value.
and I dunno if villain (probably an abc-type tag) would turn a 99 sort of hand into a bluff with the turn K if you check, but I see what ur saying.
