We got to Zion NP in the late afternoon and I didn't feel up to a climb to the Pools.
We took the Riverside Walk - more or less flat and paved. The light was pink as the sun was going down. We saw a stag crossing the river to meet up with 2 does and my husband saw his first (tiny) snake outside of a zoo.
We stayed at Mount Carmel Junction, so travelled through the Zion-Mount Carmel Tunnel both ways - fairly spectacular.
We returned next day to Zion for a morning hike up to the Emerald Pools - again fantastic light that changed by the second. The Fall colours added to the enjoyment. The reflections in the Upper Pool were spellbinding, despite someone having chucked their picnic food in to the pools - take your rubbish back with you!
We got to Zion on 29 October and this was the first day you could drive the Scenic Drive - would have been happy to take the Shuttle, but didn't see one.
I can only say - just do it, you'll get enjoyment whatever your level of fitness/mobility.
