buying a new monitor that needs to last me the next 10+ years

hi guys, i currently am using a 24 inch samsung odyssey g3 from 2021, its 5 years old now roughly and its alright, i like it for the most part, my biggest issue with the monitor is actually its size, 24 inches just feels a bit small
the main reason why i think this is because im using my monitor from 100-125cm away, im using my pc from my bed, my desk is near, and my keyboard and mouse are on a moving night table so it is a bigger gap than usual and i think you all can understand why i would prefer a bigger monitor
the resolution (more specifically PPI) is actually pretty alright and i understand that by going for a 1440p 32inch monitor, the PPI will be exactly the same basically, ill only benefit in sharpness aspect from a higher resolution on a 27inch monitor

so my first question is
should i buy a 27 inch monitor or a 32 inch monitor? is the difference between a 24 and 27 inch big enough? or it is more of a half ass upgrade?

question 2:
should i buy an OLED? theyre currently pretty cheap (relatively speaking) and can be found for 350 or so euros/usd which is pretty good
but.... i know that oleds can have burn ins, my 5 year old samsung a51 has quite significant burn ins and this phone is a phone with an OLED screen, my sisters samsung a12 which has a regular LCD display has no burn ins despite it being around the same age as my a51

will burn ins be an issue? i plan on using my new monitor for the next 10 years or so, i dont upgrade monitors very often

question 3: do OLED monitors develop green/white/pink stripes? as can be seen on some phones with OLED screens?

question 4: if the answers to questions 2 and 3 are a YES, is it better to buy an IPS or VA panel monitor for longevity?
i forgot to mention but my pc is nearly turned on 24/7, i almost never turn it off, if that information is necessary

i also have a gtx 1070 and a ryzen 5 5500, yes im aware that these arent considered "1440p gaming" components, but i dont play modern AAA games, i play old 2D and low poly 3D indie games like undertale and ultrakill and such and also nothing "professional" in a sense where i would need the highest colour accuracy but that is still a nice thing to have regardless!

my budget is 400 euros or about 460 or so USD
what do you guys recommend for me to buy? and what sites should i use? there are local IT shops near me but i do live in a small town so if there arent any good options in those stores what internet sites do you guys recommend for shopping for monitors?
