If you're gonna go docker definitely do the AIO. As huquad mentioned its the official docker deployment method, and its the best docker implementation I've used for Nextcloud, and I tried em all.
With Ubuntu on that laptop, look into the snap package for nextcloud server. Everything I've heard about it is that its a great and pretty easy was to get a nextcloud server up and running.
You might be better off with an LED panel. Something like this, which can run off an ac adapter.
But as the other commenter mentioned, if this is running unattended for 6-8 hours safety is a big consideration. Be aware of the heat these lights will generate and the safety of the electrical cords and connections you plan to use.
We need more details to recommended something to meet your needs.
What are you photographing? Is it a large object/scene, or a smaller object/scene?
How many hours on end do you expect the flash to run?
How much light do you need the flash to output? A lot? A little? Is this light meant to be the main light for the photo or is it supplemental?
Running a flash for hours on end flashing 1-2 times per second can quickly overheat a flash, which can lead to problems. The lower the flash output, the better it will handle that heat and the longer it will be able to run.
But with that being said, depending on how many hours and how much light you need you might be better off with ac powered LED light panels instead of a flash.
I'd encourage learning. The more you understand the better you can control your data and maintain your services. You don't need to be an expert but I'd encourage working towards relying less on gpt.
I'm currently fighting with my OliveTin config file. I added a simple new config for a button action and ylthe whole thing just shit the bed. Now OliveTin won't load at all. Even after removing the new config. Stupid yaml.
UP:
After reading the Jellyfin docs and their Hardware Encoder Quality section which states
Apple ≥ Intel ≥ Nvidia >>> AMD*
I decided to spin up a test server on the m1 mini that's been sitting unused in my basement for a couple of months now to see if I can get better performance out of jellyfin on the m1 vs where it's running currently, which is on an i7 Intel that's going on 10ish years old now.
I also spun up baserow and directus containers to see which one I want to use for my database needs.
Audiobookshelf for sure. It handles audiobooks fabulously, and it also does handle ebooks.
I use it to manage my eBook library, but not as the reader. You can set up a "send to ereader" option to email the ebooks to your reader of choice. So I just shoot them off to my pocketbook ereader when I want to read one.
Easiest way would be to just add a sleep 15 command at the top of the script. Time how long it takes your wifi to come up, and adjust the sleep time with like a 2-3 second buffer in case it takes linger for some reason.
More exact would be to create a systemd service for your script that depends on network connectivity to execute.
Making Mat's parents deadbeats was just crazy to me.
