New user moving from old ubuntu server to Unraid

Hey everyone, new Unraid user here

For the past 6+ years I have been using a small selfbuilt Ubuntu box, it was essentially my playground for a linux server that posed as a NAS, a download machine and over the time grew to also host a few services for me, namely Nextcloud, Ampache, Dokuwiki and two Foundry VTT instances, all reverse proxied behind apache.
Just one very small SSD for the system + one HDD for data, 8 GB RAM and powered by a AMD E-350 dual core APU. I built the thing when I was a poor student so it was all very tightly budgeted when I first bought it. The Ubuntu system has survived many dist-upgrades and while the desktop has become a tad unstable (Firefox/Chrome are prone to crashes and I get cryptic "Error has occured" messages daily), the underlying system was still performing OK for the growing workload I gave it over the years and I was mostly operating from Terminal anyway, or at least trying to.

Now I have less time, but at least a bigger budget and I thought I should stop living the dangerous live of a single hard disk system, the case and the board and the power supply in the existing box did not offer much in upgradability anyway, so I got me something new... and decided to throw Unraid onto it.

The system is already up and running fine so far, but now I am wondering what the best course of action is to move my stuff over.

It seems sensible to me to dockerize everything now, but I am still very new new to this and was hoping to get a few pointers on how to best tackle it.
Nextcloud and Ampache both sit on the same MySQL database instance, Dokuwiki is just textfiles, Foundry VTT just needs the reverse proxying done by Apache.
For most of my services I use I have already seen ready made Docker images, I figure seperating Foundry will be very easy as it is its own node environment and not reliant on anything else. I wonder most about how to best go about Nextcloud and Ampache. Ampache I can ditch if there is no easy way to go about it, I just use it very sparingly anyway so Nextcloud is what I would like to get running first primarily for my daily synching and calendar needs.
So the least I would need is two docker containers, one for the webserver and one for Nextcloud + DB, is that correct? For webserver I have been using Apache just out of habit, having learned to use it in school, I am comfortable with switching to something else if recommended. I have seen Traefik mentioned often.
Same can be said about my old Nextcloud instance. It's running on MySQL now but if the existing docker images are using something else, I do not worry about making a switch as long as I can export my DB without any issues. I have yet to take a closer look at the existing Docker images in Community Applications for Unraid and what the differences among them are.

Best end here before I keep on rambling and thinking out loud . I am looking forward to any tips and guidance you people would like to offer. I will take my time to move stuff over anyway so this is nothing that will/has to happen ASAP.
