27" 4k is going to be pretty tough to read text at 1:1 scaling even with 20/20 vision. IMO you're better off grabbing something like a 25" 2560x1440 monitor. You can comfortably read text at a few feet away, even small text with not the best contrast. If you start scaling to 150% or 200% with your 4k display you'll end up with the same screen real estate as a 2560x1440 or even a 1080p monitor depending on how much you scale up and you'll end up paying a lot more. For example a really good 2560x1440 monitor will run you about $300-350 (IPS display, low input lag, good color accuracy, etc.). The first 2 monitors in OP's post are $1,500 to $1,730. I did a huge write up on this at https://nickjanetakis.com/blog/how-to-pick-a-good-monitor-for-software-development https://nickjanetakis.com/blog/how-to-pick-a-good-monitor-fo... if anyone is curious. I evaluated a bunch of monitors and ultimately picked a 25" 2560x1440 since it's the sweet spot for PPI at normal viewing distances while having normal vision. For programming, having a 2560x1440 1:1 scaled display is going to be a huge win. You can easily fit 4x 80 column windows side by side in most code editors. After using that set up for years, there's no way I would ever want to work on a display that's less than an effective 2560x1440 resolution again.
