Mont Blanc is visible from central Geneva on a clear day, but you have to travel into France to see it close up. It is possible to squeeze in Matterhorn and Mont Blanc in 2 days but it would be an effort.
Geneva – Chamonix is not easy due to the construction of the new Leman Express cross-border rail network (opening December this year) , but there are buses
Then you would take the Mont Blanc Express Chamonix – Martigny, then SBB CFF main line train Martigny – Visp, then MGB train Visp – Zermatt, the you would return Zermatt – Visp – Genève.
The trouble is you don’t see Mont Blanc easily from central Chamonix, so there would be extra time needed to work out how you want to see the mountain (eg on the Aiguille du Midi cable car)
Try the German railways on line planner:

Input Genève to Genève and input at least two ‘via’ points (eg Chamonix and Zermatt)

If you could see only one, would it be Mont Blanc or the Matterhorn? I spent a semester in Switzerland in college and neglected to see the Matterhorn, which has always been a regret. So I am leaning towards that if only one option.

Hello czr1, and welcome to MySwissAlps!
Congratulations for your interest for the alpine peaks!
< I would like to see both Mont Blanc and the Matterhorn >
The problem is that these peaks will in a way decide if they want to show themselves to you, or not. See the attached photograph of the Matterhorn as it showed itself to me when I was there in June 2018. You could experience the same.
Reliable weather forecasts in the Alps do not go beyond four or five days.
