HDD or SSD for a home server?

I’m new to this stuff so go easy on me.

So I want to get into selfhosting, and I’ve decided to get a Raspberry Pi 5. I plan to attach drives to it, from about 500GB-1TB. I’m on a budget, preferably under $100.

I want to host these things:

• A personal lemmy instance
• A samba server, to store files and backups
• A mail server
• A few other light docker containers

I was wondering whether I should get an SSD or an HDD for these. Lemmy would probably like an SSD because it uses Postgres, but an HDD would be better for storage since I get more GB per dollar.

What should I go with?
