FOLD PRE.
KJs from UTG 8-handed is just not that strong. You have to act first now and throughout the rest of the hand (assuming the blinds don't see the flop).
You'll never have TPTK, and rarely have NFD. You'll be calling down AK and KQ on K-high boards a lot and get out-kicked.

UTG at 8-handed is like a 5% range for me. UTG at 9 handed is 4%.
I'm folding 88- from UTG most of the time (as a standard when I sit at a new table, based on player-pool reads). Once I have table reads, I can loosen up. I just need to know that villains are paying off flopped sets at a high enough rate for me to play those low pairs OOP.
Yes, I'm nitty tight, and you certainly don't have to be THAT nitty tight, but if you're going so far as to double those ranges PRE, that's too loose, IMO. You'd need near perfect post-flop play to remain profitable. No one at 2NL has that good of post-flop play. No one.


Oh wait... you're on a half-stack...
DEFINITELY FOLD PRE.

right?

Your SPR is forcing you to get all-in in more situations, so you want to start with a tighter range, so that when you are all-in (which you expect to make that decision in each hand you play), you are more likely to have the best of it.
right?
