Hello GardenData61371,
I tend to lean to the solid stable LTS versions of Linux.
I'm a Ubuntu LTS fan and use the different buntu distros.
I like the tried and proven stability of the older software that has most if not all of the bugs stomped out and removed.
Manjaro is a good Linux Distro and if kept updated runs without problems and does have the newest software.
New software isn't always best as it may not have all of the bugs stomped out and removed so may have issues sometimes.
Rolling releases do tend to have problems after new updates although if wanting to learn than rolling releases can be a good educator.
Both Ubuntu and Manjaro have good informative resources and documentation available.
Between the given choices I'd either do as the Wizard suggested in post #5 or use Ubuntu 18.04 LTS or one of the buntu flavors which are all excellent imo.
After all Linux is about choice and offers many.
