The goal of Linux is to offer everyone a different OS tailored to suit their needs, instead of there being a single OS that you have to adapt to with Windows or Mac. You articulated the point pretty well without actually understanding it.

I'd suggest (in order of my preference) Ubuntu, Debian, Mint.
Stay away from anything RHEL based like CentOS or Fedora if you're new to linux.
Don't even think about Arch or Gentoo.

antiX, myself.
Recently installed Miyo from Devuan.  Like it.
Use old machines.  No systemd.  No UEFI.
With newer machine and being a photographer, I think MX would be more suitable.  It's Debian, but much easier to install and get running.

I owe @xAcid9 a apology and @Nayr438 for that matter. 
 
This idiot was reading the online manual this afternoon for my Gigabyte X570 motherboard and no I hadn't set something after all.
 
The SATA mode selector was set to 'AHCI' which lists drives listed as external. Change to 'RAID'  and the following appears...
 
Sorry people.
 

 
 

 
To add, this is very strange as my other PC also running a Ryzen-Gigabyte setup with a 120 GB SSD plus 1TB HDD, if you set BIOS to RAID the PC will not boot into Linux?!

If it's any help, I upgraded my FX4350 for a Ryzen 3200g but was a little underwhelmed by it's performance. On it's own it's a great chip, but when I paired it with a RX570 it slowed right down remembering it's only got 4 cores, 4 threads and part of that is built in GPU. I end up upgrading to a Ryzen 2600X which has 6 cores and 12 threads and has far better performance and to be honest if you mind not having the latest CPU there are some great deals to be had on the previous architectures like the Ryzen 2600 with cooler for £120 / $100 on Amazon which would be a better match with your RX470.  

What's your budget ? 
What is the 3100 priced at ? 
Out of these two 
The 2200g and the 470 will be a better option 

Just keep in mind. On my system, when the drives are mounted in fstab. They do not show in nautilus, but do show in dolphin.
When you are setting them up in fstab, if that's the direction you continue to go, just set the mount path to a familiar directory, rather than /mnt/name
I keep my large hdd under /storage for example. my wife keeps her drive mounted as Games in her home folder.
 
Don't re-use the fstab I shared, as your root and swap partition will probably have a new uuid.
 
If gnome has something to handle this, I have no idea how it works or what it does. I can only offer fstab help.
 
On a fresh install dolphin lists them as removable drives until they are added to fstab, upon reboot they are shown as non removable drives on all of my systems.

I use Arch and would personally recommend Manjaro KDE Plasma if your uncomfortable with setting up Arch without a installer.
Ubuntu does weird things and ships fairly outdated packages, I personally have a lot of complaints with Ubuntu. But that's just my opinion.

So this is what I got, not sure why you had 2 swap partitions. This only has the nvme one.
sudo umount /dev/sdb sudo umount /dev/sdc # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> # nvme root file system UUID=ab41d663-2d4f-4bc3-bab7-dea3689f6ce5 / ext4 defaults,noatime,rw 0 1 # nvme swap partition UUID=4e8c2619-7633-4226-a57b-2926b5eeb855 none swap defaults 0 0 # movies UUID=476c835b-21c8-43fc-800f-7582ab80108e /mnt/movies ext4 defaults,noatime 0 0 # photography UUID=a2e22bc9-3909-45d8-8a89-7ed0a17b7b8e /mnt/photography ext4 defaults,noatime 0 0   sudo mkdir /mnt/movies sudo mkdir /mnt/photography sudo mount -a if you get any errors, do not restart until its fixed. sudo chown -R $USER /mnt/movies sudo chown -R $USER /mnt/photography

Oh well!  Since OP familiar with Debian, was going to suggest MX or antiX.
Manjaro ain't bad, though.
Current 'buntus are too buggy for me, personally.

Just try to use the Gnome-Disks app, it's more like a fstab frontend and you can edit everything from there

It may list them as external disks if they are not part of fstab. I am fairly unfamiliar with gnome and nautilus, I never cared for gnomes work flow or applications.
yay is a pacman and aur helper, it has to be built and installed, instructions in the link. you do not need to use sudo in front of yay, it will ask for a password when its ready to install something.
pamac is manjaro's default package manager and has a GUI, pacman is Arch's default package manager and is terminal only.
for pacman and other root tasks, you need to do sudo.
