I tried HLG extensively when I got the GH5 but struggled with proper grading as I do not have an HLG monitor. Of course you can look at the curves but the whole colour balance is different and at the end for underwater use I abandoned it
For land shots already white balanced it works great straight off the camera for me

You can transform it to REC 709 using a LUT or color space transform node in Davinci Resolve. Thats the best option if you want to work with it and dont have an HLG monitor. To be honest if you just throw the footage to a REC709 timeline and the footage doesn't need drastic changes (the profile is not designed for that anyway) it will be fine for 99% of the viewers. If your shots are all balanced light shots it works fine. Remember that HLG is designed to have backwards compatibility with SDR.
I don't see anything in the below videos that would've turned out any differently had the footage been shot in an 8bit codec and the standard or cine-d picture profiles on the GH5, to be honest. There's no real highlight rolloff underwater except in rare circumstances where you're shooting up towards the surface (those shots don't look so natural in this footage, log or not) or blowing out your foreground illumination in mixed-light shots.

I found these two GH5 videos shots 4K 400 Mbps (4:2:2 ALL-Intra a 10 bit). Picture profile V log L and Color Correction with Da Vinci Resolve 15 Studio
In this you can see before/after:

I agree and actually in Bahamas I shot against the surface with a filter and there were no problems in cine like D 10 bits 10 bits does make a difference if you watch it at home but YouTube runs the blue giving banding in the tricky situations
