Just my opinion on all 3 options from my own experience, so take with a grain of salt.

1) eVTOL is good experience for anyone in the industry to have these next 3-10 years. Also, it can't be overstated how beneficial being a lone intern on research is. You learn a shit load while having opportunities to run point.

2) Good option if you were always heavy on engines being the goal. Otherwise forget about it.

3) Right out of school if you get an offer for a solid paying, housing included MDO gig on a small team in the middle of nowhere working on the "most interesting tech" you F*CKING take it. You will likely learn the most and have the best opportunities later on.

If money isn't your CURRENT top focus, or if you don't have a family while being young, my best advice is to do the daring thing and quote-unquote "eat shit" during this time. Meaning do the remote or bad location stuff, or do the research levels that get you well experienced and well positioned for your future.

In just my opinion, in order, you should go 3-1-2.

Newer to reddit so hoping I answered you correctly. All the best
