I’m still fairly new to game development

You are considering making a multi-mode, live service game as what I presume is a solo developer.

Make a single player game centered around a single gameplay loop. Get it working well and make it fun. Keep the scope under control.

Once you can do this play around with more complex gameplay loops in single player games but always keep your scope manageable and planned out. Write yourself a game design document that outlines the scope and general objectives of the project and stick to it.
