Wishing to install a dishwasher in an old home while retaining the cabinetry. To the left of the sink area is more than enough width, requiring removing some drawers and doors and re-trimming, but smack back on the wall is a two inch cleanout for the vent pie. Cast iron. This protrudes in enough that I don’t have the depth for the D/W, so it must come off. I read the parts about how to cut cast iron, and I think I can get a Sawzall to the cleanout. Any thoughts on the best way to seal the hole afterward?

I used a sawzall with a metal blade and had excellent results, but it took about 4 blades for a 4" pipe....
Milwaukee and Lennox make blades especially for cast iron. I have cut thru 4" cast iron in a couple of minutes.
If you are able to rework the cabinet placement you would be ahead if you could move the dishwasher placement a bit further to the left to miss the cleanout.
But, if cutting off is what you want to do...........
There are Fernco caps with the stainless band available that may fit on the stub of the cutoff pipe, if you can leave enough pipe stub to clamp the cap. Otherwise you'll have a real hack job.
Seems to me like there are some code requirements for at least the placement of clean outs. You might want to make sure that what ever you do still allows code to be met
You are saying the clean out is stubed out of the wall and through the back of the cabinet? Or maybe the cabinet has no back and the clean out is just stubed out of the wall?
Either case, remove the cabinet and/or open up the wall. If the ci is a lead/oakum joint cut out the clean out and either reinstall a staright run of pipe or another clean out at parallel to the wall face. Use no hub connectors,Fernco or Michelin bands, and support the ci above and below the cuts before you cut it out. Replace the wall material with a plywood panel of the same thickness screwed to the studs ecah side of the access point.
A lot depends on the type of ci fitting the clean out is in. A cleanout hub tee would project out of a 2x4 wall about 1 1/2 to 2 inches. a clean out on a short wye would stick out of the wall abot 4 inches. Either one could be rotated into the plane of the wall if they were areaddy installed with nohub fittings.
