Thinking about getting these items for my new desk/battlestation setup. Any thoughts or advice?

I’m finally putting together a major overhaul for my home office and gaming setup. I do a mix of video editing/productivity during the day and PC/PS5 gaming at night.

After doing a ton of research, I’ve put together a list of components I’m planning to buy over the next couple of weeks, but I’d love some final feedback. Here is what I’m leaning toward:

Herman Miller Embody: My current cheap office chair is absolutely killing my lower back. The price is obviously insane, but it seems like the general consensus here is that it's worth every penny for long sessions.

Hisense 55" U7 Mini-LED: I need a secondary screen for casual controller gaming and monitoring stuff, but I really didn’t want to pay OLED money for a desk setup. The 55" U7 seems like the perfect sweet spot, it has a native 165Hz refresh rate, AMD FreeSync Premium Pro, and decent local dimming for those deep blacks.

SteelSeries Arctis Nova Pro Wireless: Swapping out my old headset for this one. I need something with dual-wireless (2.4GHz + Bluetooth) so I can stay connected to my PC and phone at the same time, and the active noise canceling seems like a huge plus for staying focused.

Logitech Lift Vertical Mouse: Switching from a standard mouse to an ergonomic vertical one to help with wrist strain during long video editing marrows.

For those who already own any of these, how has your long-term experience been?

Would appreciate any thoughts or alternatives I should look into. Thanks!
