I would say, focus less on a server and more on finding a person or small group who have similar limited times to rp but whose limited times correspond with your limited times. Check out server discords, post in making connections here, dabble in tumblr. Putting money down after finding a group who will celebrate your ability to be online with what limited time you have and understand (perhaps even empathize) will be a much more rewarding feeling than casting about and feeling lost and frustrated.
However, do note that finding people who match all your needs will take some time and energy investment for you (unless you get lucky). There's no rush. Take your time, do it when you have the time, and learn as you go. There are some really phenomenal people here, but as with most things if the social aspect of the game is what really sells it for you, try to find that first.
