I think the first question would be more towards what are you trying to create? Where are you coming at this program from? You’ve stated that you’re new to 3D sculpting, but do you have a lot of 2d experience to draw from (bad pun intended…)?
As you’ve already found the forum, you can see that just about any question that you have can likely be answered right here without the need to pay for any tutorials. And it would be tailored specifically to the project that you’re trying to create. Plus, the actual creator is here and quite active. You rarely see that anywhere.
My recommendation would be just to have fun to start. Test out the tools to see what they do. Sometimes the “happy little accidents” can teach you quite a bit about what the program can do for you. For the most part, you’ll only be using a few tools for 90+ percent of your time sculpting. Start by turning on the dynamic topology so you’re mostly focused on just sculpting and having fun at the beginning. Use the Brush (or Clay) tool to build out what you’re trying to create. The Move tool can make large or small adjustments to put things into place. And then the Smooth tool to smooth out little areas. The rest of the tools are likely going to be used when refining what you’ve already done and can be figured out when you get to that point.
There are no right or wrong ways to use Nomad, so just go wild. Just my two cents anyway.
