Welcome to new home ownership!! I’m going to assume right off you mean power tools and OPE.
Let’s start with power tools in order of importance:
Drill/impact driver combo kit, your going to be doing a lot of fastening from cabnets to furniture, fixing doors and hanging stuff. A combo kit will get you into a cordless tool line with typically 2 batteries and a charger.
Circular saw, it’s a staple in any home, sometimes something just needs to be cut quickly and cleanly. You can get a cordless one that matches your above combo kit but most of the time cordless saws just don’t quite cut it(pun), get a 15 amp corded model, for $50-100 you can get all the saw you’ll need.
Receipsaw, this is just handy for everything from taking out a wall, cutting down a fence posts to even pruning trees and shrubs. I’d suggest getting a cordless one only if you plan on getting a couple extra batteries and match it to your combo kit otherwise a good corded one can be had for well less than $100.
A grinder, I use mine for cutting off old screws, nails to sharpening mower blades. I use a cheap corded Black & Decker one and even though I’m a professional builder it’s all I ever needed.
The rest of the power tools tend to be more specialized, and kinda " you’ll know if you need it" stuff.
Mower, small lot, look at a battery powered model that can maybe work with the batteries you have for your cordless tools, and other OPE.
Weed whacker, gotta get those close cuts, around trees, against the house and garage, again battery powered to match your tools makes sense.
Blower, if your anywhere that leafs fall it sure beats a rake. Also battery to match.
As you can see alot of my suggestions involve battery powered tools and many tool companies make both categories. As a builder I use DeWalt for my cordless building tools, a little higher end than an average home owner needs but they make all the above products and who am I to tell you not to get high end stuff! I also have some Ryobi stuff that fit a niche that I needed and I chose them for my lawn care tools, my wife absolutely loves the 18v mower.
All that said I highly recommend Ryobi for everything on the list, the green stuff is really quite good these days and their extensive cordless tool lineup has most any tool you could ever need.
