Capping PEX stub temporarily

I'm at the lowest point in the house and have a PEX stub for heating coming out the wall....
In the midst of a remodel....and cut the baseboard about about 3 weeks ago !
I dunno if it's the weather but it was done *dripping* for a bit but for the last 3 days, tidbits of water has been coming out of the open stub...


I'm about to start tiling, etc and wanted to just keep the water from coming out of the pex stub until the baseboard is one.
Thoughts, suggestions....

Shark bite cap is your easiest and best way for a temp cap.

John Guest cap is much cheaper and a lot easier to remove when its job is done.
