I don't shoot RAW anyway, and even for JPEGs I always fret about the goddamn photos taking up too much space. Of course, I try to cull as many of them as I can, though sometimes I only get to it after a few months. :-)
Regarding archiving point, one thing I am really happy about is that in past 5 years or so, I have digitalized and organized (rather simple approach) most of my photo archive. Stored (and backed up) on external HDD(s), I use Plex as a server to host selected parts of archive. Whole family, including teen kids, have accses to it. And they do use it on mobile or notebook and love it doing so. At least I am told so. :-)
Works like a charm.
