I'll apologise now for the tiktok link, i know how much this place hates tiktok but here is a woman who did a deep dive and found evidence that the company actually changed their logo and tried to scrub the existence of the Cornucopia from the internet to distance themselves from Bad PR.

Likely not the solution you're looking for but a buddy and i link a folder via syncthing and anything added to one side shows up on the other.
Most of that will be budget based and long term goal oriented. Do you want a 4 bay nas with 10tb drives set up in raid 5 or do you think you'd want a two bay system with 5tb drives set up in mirror raid? Do you want to start cheap and get a second hand thinkcenter off ebay or do you want to buy a brand new NUC and put a 2tb M.2 and 16gb of ram in one slot so you can add the other 16gb later? Some nuc can take up to 64gb of ram and have two 2tb drives in them.

According to this it's still planned, though time will tell.
To play off what others are saying i think a mini pc and a stand alone nas may be the better route for you. It may seem counter intuitive to break it out into two devices but doing so will allow room for growth. If you buy a creeper bare bones mini pc and put more of your budget towards a nas and storage you could expand the mini pc without messing with your nas. You could keep the pi in the mix for a backup if your main pc is down or offload some services to it to balance performance.

It lacks predictive text but it's in development.
It's a great software to run. I like to watch youtube tutorials that explain things step by step so i can understand what happens. If i find a good video i'll see what other software that channel may have a tutorial on and if that software may interest me.
You could set up a dns based ad-blocker like pihole and a vpn like wireguard to tunnel your phone back into your home network so you have ad-blocking on the go, too. That's a semi beginner protect with plenty of tutorials to pick from.
You could run nextcloud, syncthing, or immich to make your own cloud at home but that might need more than a basic pi setup.
