Thanks All for you feedback, it’s been extremely helpful.
I’ll give Waydroid a try.
That will mean upgrading to Lubuntu 25.04 or 25.10, something I don’t like to do (I try to stay with the LTS versions). But I’ll make an exception here. “Aim for the stars, at worst you’ll land in the trees.” 
I’ll let you know how it works out.
Cheers.
