I have a concrete patio that has a few cracks (minor) in it, plus some
rust stains.

Is there anything I can do to cover this up to enhance it?
I am thinking pavers, or some decorative rock, and not carpet or
painting over it. Also, hopefully, there is something I can do
myself, rather than hiring it done.

Concrete isn't repairable.

Putting something on top will probably come with issues.

I can tell you what I did:

1. Rent electric air hammer, break cement into pieces.
2. Call carting company and have rubble removed.
3. Dig to required depth and lay rock dust and sand.
4. Pack with rented vibrating compactor.
5. Lay pavers on top.

Lots of little details like edging, getting the right run off, etc.
But assuming you don't want a hack job...
