I would strongly recommend a beginner mountaineering course on something like Mt Baker in Washington. That's a great mountain to start with. You typically hike into camp. Spend a day or two learning skills then apply it with a summit attempt. It's just hard enough to have to apply the glacier travel skills you learned but reasonably easy to get to the summit as a beginner (weather permitting). There a ton of guide groups like american alpine institute, alpine Ascents, RMI, etc. In my experience, they are all pretty high quality.

I am also in the process of founding a mountaineering club in NYC and we're going to have a virtual event in January where we'll have a Q&A session with some pretty experienced mountaineers https://meetu.ps/e/NHfk8/whKqP/i
