Lucius gave you good advice, so I'll just throw in some tools that can help you work with disks.
I will echo one thing tho, you prob want the cloud in there somewhere, because if a disaster strikes your house, block, town, or you're concerned about political instability having copies of that material in a very different location is GOOD.
What works for me is the combo of
(1) MakeMKV (to duplicate a full disc image to HD)
(2) Handbrake to extract video files from that (now unencrypted) disc image
in my ewaste scavenging, i sometimes find people's old boot disks they kept around for emergencies. from what i can tell, you put together just enough of an MS-DOS installation for the computer to boot up again when everything else was going wrong. you feel a sense of connection to someone from 30 years ago - we're both just trying to get these things working again and hoping whatever ails our PC is within our means to fix. they seem personal, they have people's names on them, they have dates and instructions. you can tell it mattered pictured: me using some of these boot disks i found in the trash to update the BIOS of an old server motherboard
Even if you end up having to go somewhere else, there still will be culture to get involved in, people to meet, things to learn, realizations to be made. All of that is still right there for you and it will be open in a way you won't even realize until you've done like a year or two. So it's truly still exciting times. As long as you feel generally good about the place you ultimately choose, your time is coming.
