Nothing wrong with partnerships - I have used one to scale way faster than I would have on my own because he brought skills I didn’t have - but if you can do a deal on your own first to get a better understanding of the entire process it may help you identify what you need from a partner and what types of things should be in the operating agreement.As for the operating agreement, be sure you sit down with an experienced attorney who will help go over the dozens of scenarios that may come up and how you would like to handle them.

I would focus on new-build multis because you will be at max rent for LTR and scalable for STR.
