How would gravity and centrifugal force interact in Dyson constructs?

I am developing an alien race whose homeworld is a Dyson sphere planetoid (they used collected planetary and asteroid matter to construct a "hollow planet" around their sun, along with "night" solar screens). The alien race has incredibly advanced bio-engineering capacity; biotech living ships, "latticework" organisms used to stitch their sphere components together, etc. They also have a younger system that currently has a Dyson ring with the same construction method.

Now, any construct that massive will have its own gravity in addition to the centrifugal force of its spin providing false gravity.

My question(s): How would gravity be perceived by inhabitants on: 1. The sphere's interior(where I am envisioning their habitation region exists)? 2. The sphere's exterior (likely their "spaceports" would be on the sphere's exterior) 3. How, if at all, would gravity/cf differ with the ring vs the sphere?

The setting is a sci-fi one and alien tech is heavily involved. So, while I am looking for plausible/realistic answers (semi-hard science?), some measure of blah-blah molecules (I like this term for sci-fi more than "hand-waving") is totally acceptable, though I'd prefer to know about things that needed such overlooking so they can have lore reasons to be non-issues.
