Wordpress with custom post types is what I'd reach for. You can install WP on any number of shared hosts for ~$10/month. Then install custom post types and you can set up attributes for each entity type. The UI is all taken care of. You can even use it to drive an API.

These instructions from me are a few years old but cover the basics: https://www.mooreds.com/wordpress/archives/2971

is custom post types a thing? i see your page says something about a custom post types ui plugin.

It is, the plugin in question just let's them setup (using UI?) easily but it's most certainly a thing on its own.
