If you're capturing on a mobile device, why not use Scaniverse? It's about as all-in-one as it gets - you just scan and it'll generate a .ply after a minute or two of processing. They'll host the splat for you in the cloud if you want too.
For me, at least, I want to own all my data, and not give any away without explicit permission. So, even in the case of Scaniverse, I'm reluctant.
But I'm just an artist trying to read and learn, and haven't yet gotten around to actually figuring out how to do all this on my Macbook Pro M1 yet ^-^
