UTG opening ranges

Hello, I mainly play $0.10/0.20 9 seated cash games online. One thing I'm not too sure on is what I should and shouldn't be opening with in early position and is it bad to limp at all? So I am talking about being dealt hands like KQ, QJs, KJs and small pocket pairs utg or utg+1. Is it best to open raise, just fold or limp?
Thanks in advance for any advice

If you are 100 BB's deep there is no problem opening small pairs UTG as long as you are careful imo, you should never be limping, hands like KQ and KJs can be opened UTG imo if you are comfortable enough with your post flop play (ie you can get away from it and know when to shut down) However i dont think you should be opening KJo, it should be suiting allowing you to win the big pots. but if you are not comfortable then you should be folding this kind of hands (KQ, KJs, QJs etc)

I like 22+, JTs+,AQ+ in any position for 3bb open. I add hands in mid and late positions but my FR stats were still pretty tight (17/13). Opening any narrower seems to nitty. Frequent open limping is a significant leak.
