The pex al pex might be preferable for you. I'll take back my initial comment about that for say kind of in the eye of the beholder. But the are people who are weary of pex al pex becuse of delamination

I wasn’t aware of delamination. I know compression fittings are easy to work with so I would use them for Pex al Pex.

For regular Pex I’d prefer using shark bite or crimp fittings as I have a crimp tool. Are neither of these fitting methods preferable for hepex?

You can use a rope of pex b that has oxygen barrier. Pex a is hepex. I think what you'll want is commonly orange.

I’m sorry, I meant I have a clamp tool for clamp connections, not crimp. Shark bite or clamp fittings for regular Pex.

will likely stick with the Pex al Pex and use a compression fitting.
