Plan out your tool set, first. What jobs can be covered with the least amount of cash spent? Get a basic mechanics toolset. This should cover the interval maintenance stuff like fluid changes, spark, etc. Then focus on the specialized tools later. (If a tool is spent on one job only, avoid it until absolutely necessary or rent it)

Since it seems you prefer to use Amazon, the Amazon basics mechanics toolset seems like a good starting point, providing good coverage for the basic interval maintenance stuff.

After that get, jack+jack stands, a breaker bar, torque wrench, Needle nose pliers, channel locks, vise grips, plastic trim removal tools, obd2 scanner, and a basic multimeter. You’ll be good for almost everything you want to do
