Unsure about building a PC could use help picking one.

Last time I built a PC was many years ago. Back when the AMD Black Edition 6 cores came out and had a GeForce 570ti. I feel guilty for wanting to build/buy but wife is encouraging me because we could always use the money for additional emergency funds. ANYWAYS... I have a nearby Microcenter and was looking at a few of their PCs. It's been many years since I've built a PC that I don't want to get the wrong parts or screw myself over by getting a good part now, but will then need to be upgraded later before I can upgrade other things.

I'm looking around the $1400 area. I wouldn't mind a 3060ti or higher. I do see some CPU Ryzen 5's but compared to the Intel 12700fs it doesn't compete well, but I'm sure I could be missing a lot of stuff by only looking at benchmarks. I'm just trying to make this less stressful and be done with the process. Typically I take months to do research but there's just so much for PC's I'd fry my brain out.

Here's what I'm looking at. Feel free to pick different things or send Amazon links/PC Builder for full builds etc. 3 PC's

Edit:typos- purpose for gaming mainly.
