I think you more or less answered your own question here - people succeed at jobs that they can sustain and I concur with that. Shitty leaders who look down on different people for their jobs are just that - shitty leaders. One caveat I'd add is that I'm an introvert myself and initially found a lot of these meetings and especially conferences, extremely draining. However I also realized that there were ways to make them not-as-draining. For example, don't go to a conference unless you are a speaker. That reduces the feeling that you need to approach people to make conversation, make small talk etc... For meetings, set the expectations that there will be concrete and measurable tasks that come out of the meeting, or otherwise don't have them. Just the facts ma'am. It's surprisingly effective, and way more efficient when you cut out the BS. Things like that I've found reduce the amount of heavy social reading, politics, etc... which are so draining to most introverts like us. YMMV
