PMF Experimenting Advice (I will not promote)

Hey y'all, so I've been working on a b2b saas startup for like 6 months now, we just started getting customers about a month ago and have a 4 fig ARR. The main thing I'm trying to figure out right now is that multiple different industries are interested in the product and theres a couple different features of the product that they each use so how can I manage all that and narrow down and make the right decision for where to focus all our time and energy. There's also one use case that I think could be big and I want to explore it and spend time acquiring customers in that space while we're still early to see if that use case/industry has as much potential as I think it might. Does it make sense to try and spend a certain amount of time doing sales for each use case/industry and based on those track other metrics on the customers we convert? I don't want to commit to one use case/industry just yet without getting real data to support which is the best opportunity for us, but I'm curious what y'all think. Thanks in advance!
