To "mass-check and mass-update" containers from the commandline, dockcheck is very light and useful. A simple dockcheck.sh -a -p for example would check all deployed containers for image updates and if there are any, pull them, then restart the container and at the end, cleanup unused images to free up diskspace. There is also a version with a web interface, DCW.

Portainer runs in a container by itself, but provides a beginner-friendly web interface for you to start/stop/etc all your containers. Community Edition is free and should be good enough, especially for beginners. But you can also get a Business Edition license for free, for up to 5 nodes and enjoy a few more special features.
Similar to Watchtower but without the option to auto-update containers, just notifying is diun. But imo it does that better and more reliable than Watchtower does. You can get notified by Email, Discord, Pushover, Telegram and many more options.
Watchtower is a popular thing to also run in a container, and it can check all your containers for updates and optionally also pull and restart them them. However there are some risks to automatically update software right away when its released. Typically i would recommend you set Watchtower to only notify you about available updates, and then you can check the releasenotes and decide when its safe to update.
But there is this little tool docker-autocompose that can read the configuration of your current containers and export that into a docker-compose.yml. It probably wont work 100% perfect for every possible container config, but its worth a try and it might save a lot of time when making the switch from run to compose. Good luck!
