I am not an Umbrel user, but I think it has a lot of tools. If you are in a good hardware, try to install and learn LNDg, test for a month and look how it handle the prices. It's not a must that you put all your channels 50/50, you are going to have some outbound/inbound focus.

Try to focus in the quality of your channels, in the other end is a stable node? Try to batch the open channel to don't paid too much in fees.

At first, the most important thing is to try to recover your expenses, how much cost the open channel? what bandwidth have? how many forwards I am going to need to do to recover for the sats I spend?

Few and bigger channels are better in this stage. What is your pub key? now I am curious hahaha.
