Paths are paved,but a bit curvy. Great views are available to anyone whether with physical challenges or no. Bring binoculars or a telescopic camera lens to check out details clearly!
The views of points of interest are all accessible from the individual areas parking areas, which are spread out in the main part of the park, along a loop drive. Note, though the paths are paved, they are not flat. You will navigate changes in elevation to get the the view points.
It depends if you're in the area or going out of your way. We went two weeks ago on a Thursday night after work. The drive back is absolutely breath taking, but as noted, most attractions were closed. You can still view them from a distance, which is still very interesting - you just wont be able to climb on the structures. I think we were through the site in about 3 - 3.5 hours.
I would agree with a few of the other answers, the drive does have some good stops for sightseeing from the car. Since you wouldn't be hiking or taking tours, going mid to late April would be the best time to start.
The cliff palace loop is currently closed for a bike path installation. You can still see it from the Sun Temple view point. It's still worth it if you don't think you'll be back in that area. All the dwellings tours are closed but the small village paths are open to walk around and look at the old excavations. Those paths are all easily accessible for handicapped or people with physical limitations.
Even the drive is pretty spectacular but I would wait until the shops are open if you aren't able to hike to the dwellings.
The longest hike from the car around the loop is maybe .3 miles. If you can go that far I say it's worth it for sure. Also definitely call to talk to a ranger they will be able to help you out better then anyone on here.
I would say no, unless maybe you have someone to wheel you around. There is alot to see from the paved road access but even then there is a hike for some and some things will still be inaccessible to you.
In the winter, you can't go into the dwellings anyways. There's a loop that you drive and you park at each "exhibit." So, you'll be getting in and out of the vehicle a lot. But, everything is reasonably close to the park spots. Call the park ranger office and ask. They were very helpful.
I would just check out those videos about Mesa Verde.
