This join has started leaking again

OP,
Change the fitting after cleaning the connecting pipes.
These fittings will leak if made incorrectly, and installed so as to be constantly under mechanical pressure.
Some of the other fittings dont look too clever - why not post a larger context view of the scene?

Fit a new T fitting, that one is obviously damaged. When refitting make sure the pipes align properly, and there are no burrs on the pipes, especially the copper pipes, to damage the seals.
One cannot 'retighten' push-fit connections...
They rely on rubber o-rings to make a seal on smooth clean copper or plastic pipes. Those can be damaged by a rough end on the pipe and/or the pipe scored rather than smooth, allowing a leak.
Option 1 is to replace with another pushfit Tee. Yours look like John Guest Speedfit to me.
Clean up and look for any scoring of the pipe that is leaking especially. Check the end isn't sharp (file / smooth it if so) to ensure the new o-rings don't get damaged.
If scored / damaged too much then replace with a compression Tee and ideally copper olives. (Copper are softer than brass so better suited to the plastic pipe especially I believe).
Option 2 is to go straight for the compression Tee as a replacement.

Can I replace this with a Hep20 fitting? I know it's fine for the copper pipes but didn't know if it will work with the current plastic pipe.

Yes, I you prefer.
Hep2O are the same rubber o-ring seal design but need a different plastic pipe insert. (Modern version). Older Hep2o could be dismantled to some extent but still rely on an o-ring. The Speedfit insert may or may not work OK with Hep2O but is probably not advised.
You have the same potential issue with that (leaking joint) copper pipe - smoothness/scoring and 'burrs' on the end damaging the o-ring when inserted.

Can I use a hep20 insert in the current plastic pipe? It may not be a hep20 pipe.
The issue seems to have been the green copper oxide (Verdigris) on the pipe. Whatever's been on the pipe or in the fitting has corroded the copper and that has then broken the seal @ the O-ring. Water off and strip the fitting down, check the seals and if they aren't damaged then clean the copper up with a green scourer to nice and shiny and make sure there's no scores/marks on it. If the seals are ok then a little silicone grease on them and remake the fitting, it should be ok.
If the copper is badly scored/marked and can't be cleaned up or the seals damaged then it's a new fitting and /or new pipe.

I plan to take a Hep20 fitting with me and I'm trying to preempt the inserts I need for the plastic pipe. I already have some Hep20 inserts. If it's a white pipe, are there many other options in terms of inserts? I could take the different ones with me and get the fix done rather than a back-and-forth.

It should already have inserts in it for the exiting pipe/fitting.
If it's HEP - JG would be a really tight fit, if it's JG then HEP will be a looser fit.
Unfortunately - some of the non branded/sheds own plastic pipe is white too but as suggested, there should already be an insert in there. Nothing wrong with HEP but if there's an issue with the pipe and the tee is fitted then they can be difficult to remove without leaving the insert in the fitting (not with the copper of course). Given it looks like JG fittings, then it may be JG pipe too
It's a major PIA with HEP as it is supposed to be fully demountable but if I had a penny for every HEP fitting that's been scrapped because they've ended up with the insert stuck in it.
