I am severely lacking in AR experience...frankly have had little to know interest in them and missed the “black gun” craze a while back. But looking to get my feet wet.
If I were to initiate a build, what middle of the road upper, lower, and barrel and cost would be appropriate? I know just like all the big boy toys, there’s no limit and the more you have to more you want mentality is ever-present.
Also just thinking that it’ll be a good endeavor to undertake with my son...good father, son time that will pay dividends far beyond the price of a few parts and ammunition.
Lowers I would say Anderson or AERO. The AERO has a screw that can be used Ed to tighten upper and lower fit. My next two builds will have a Rise Ammerment trigger and a buffed mill spec trigger. I currently have a Trigger Tech 2 stage trigger and would like to compare the three. I know I don’t shoot a 7 pound mil spec trigger very well. I will probably be getting more Bear Creek Armorment uppers from my limited experience so far you are going to have to spend a fair chunk of cash to shoot any better. Even if you want to change barrels later your still not out any money. I do like an oversized ambidextrous charging handle and that’s one thing I would eventually change. I would like to try a side charging upper at some point. Cartridge is all depends on what end use is.
I would use a inexpensive upper and lower, aero precision, Anderson, etc spend your money on a decent barrel and trigger.
AR Performance makes some really good barrels at a decent price, they will also sell you a bolt matched to your barrel. I have several ARP barrels, all are shooters.
You can buy better but they cost a lot more money.
you can get a receiver lapping tool for not a lot of money, its money well spent IMO, lap the receiver, then install the barrel.
Caliber??? most build .223 but there are other good choices, I like my 6.8 SPCs for a do all AR, .223 is fun to play with and to shoot varmints with but a 6.8 or 6.5 Grendel makes a fine deer cartridge, some argue that .223 is a good deer round, I beg to differ. I have killed several deer with .223 using 70 grain Barnes TSX and it gets the job done but its far from ideal.
Remember, good barrel, good trigger, not necessarily in that order. Right now is a great time to build an AR, better than it's been since before Bill Clinton, parts are plentiful and cheap.

The Grendel is hard on bolts, If you go that route get a really good bolt, ARP makes some of the best out there, the Grendel also needs a longer barrel to do it's thing, if you want shorter than a 20" tube you are much better served with the 6.8. It's just a good all around caliber, I no longer own a Grendel but I have 2 6.8s, not that it means anything but I like a short barrel and the six 8 does it thing in a 16" barrel.
My 16" 6.8 without a flash hider is 31" long with the stock collapsed which makes it my favorite tree stand gun during gun season, it's accurate, light and flat out stomps deer with the 110 sierra pro hunter, it makes for super fast follow up shots if needed and IMO is the perfect set up for a kid or female, low recoil and can be adjusted to fit anyone, the Geissele trigger is as good as any trigger I have ever used.
Bill what velocity are you getting with your 16” 6.8spc and 110’s? Bills descriptions on cartridges is good but I would like to mention 3 other cartridges. 300 blackout I feel has use in short range hunting say out to 150 yards and can go quite If you decide subsonic is for you. The 300 Blackout was designed for short barrels and if shooting pistol length set ups deserves a look. 450 Bushmaster a straight wall cartridges that is legal in some states slug zones. The 450 Bushmaster uses .452 pistol projectiles. 458 Socom is designed for supersonic and subsonic shooting useing .458 rifle bullets.
When building a Grendel or 6.8 pay attention to “Type II” I believe it to be how deep your casing seats in boltface. Grendel and Grendel Type II barrels and boltfaces are not interchangeable.

I'm thinking 2500 or so but it's been a spell since I checked it. The AR has come a long way in the last 20 years, they can be built to be very accurate and do pretty much anything you want to accomplish.
With one lower you can have a multitude of different guns with the pull of 2 pins and a simple swap. They are the jeep of the gun world.
Find a way to escape to the outdoors with no tech... Phones, etc stay home. Building a couple lowers wil be a good way to start. Spend time together using them. Coyotes, groundhogs, etc. But its tough to get kids away from their phones. If I could I'd throw mine in the deepest body of water I could find. LOL
