Looking to upgrade my home office setup.

Maybe I am too late for this, but I have a very minimalist setup currently at home. IMO it needs major upgrades. I am looking for following things to buy, feel free to share your recommendations. 1 - Height adjustable table (ergo you finalised) 2 - A ergonomic chair ( budget 15k max) 3 - ultra wide monitor 4 - good headphones (budget 30k max) 5 - keyboard and mouse ( using apple ones seems to be working for now) 6 - storage unit (finalised one from ikea) 7 - laptop (one personal one office) - laptop stand might be too much 8 - desk mat - (one from daily objects seems swanky) Is there anything else you would add/remove to/from this? feel free to share your thought process behind building a home office setup.
