Arch, of course.

Ubuntu is a good starting point.

You can follow the general idea of: "Are you new to Linux? If yes, use something you know other people know too. If no, use whatever the fuck you want, heck, make your own distro if you want".

I'd say try whatever looks good to you, you can always install something else if you don't like it, as long as it isn't Manjaro. (backup your data before you install something new)

Some distros that I think are a pretty good choice for starters (no particular order):

• Pop!_OS
• Ubuntu
• Fedora
• Endeavour OS
• Linux Mint
• openSUSE Tumbleweed

You can also use Distrochooser to maybe help you make a decision.

Not a great programmer but I’d like to learn.

That's alright, you don't have to be a programmer to use Linux. You don't even have to use the command line if you don't want to (tho I recommend it, getting good at it feels pretty great).

Any general purpose distro will work well for you. As others have said, Ubuntu and Mint are the standard recommendations.

Additional to the Mint suggestions: Mint tones down the "Ubuntu-ness" of their default distribution, but it's still Ubuntu under the hood. LMDE is the version of Mint based on straight Debian skipping the Ubuntu "middle-man" if that sounds more appealing.

Can't speak to compatibility one way or another, though.

My computer is old and made of parts from well-known manufacturers. Everything in it is pretty well-known to the open-source community at this point, so that might well be giving me a huge advantage with regard to drivers and such. (Case in point, I have an NVIDIA graphics card and Intel i7 from the tail end of the era where people wouldn't advise you against getting either, and in fact might have outright recommended them over AMD. Yes, that old. Legacy proprietary drivers work fine for me.)

Linux mint hands down

Whatever distro looks good to you is a good place to start. Think of distros as default configurations, you can basically change most stuff whenever you want.

Avoid Arch, just in case.

Debian with GNOME

Suggestions: Linux Mint: this is the most popular recommendation for new users. Its nice and stable, uses a familiar Windows-like layout, and should just work out of the box. Pop_OS!: this one is another popular option, which uses a layout similar to MacOS and has lots of features such as window tiling. It does use older package and isn't often updated, however. Zorin OS: this one is pretty similar to Linux Mint. It also offers some additional desktop layouts, but some of these are paid, so if you want an entirely free experience, this is not the best option.

Suggestions for if you enjoy suffering: Arch Linux: Requires manual installation. You have to download and configure all the things yourself. Good option for advanced users who want complete control over their system and all packages installed on it. Otherwise, stay away. Arch-based distros (Endeavour, Garuda, etc): Far simpler to install, but will likely require regular maintainance, due to frequent updates.
