As always it's each to there own, to do as you please or suits you. Unless I was doing 18-20,000 miles in 12 months or under I would have the oil changed every 12 months anyway, just ask or tell the Dealership to do that, they ain't gonna turn the money down, as for warranties AFAIK in Europe the work don't have to be done at an official Dealership as long as the work done and parts and materials used are good enough. As for hot oil, note I put warm (hot), whoever is doing the work is responsible for Health & Safety, theirs and other peoples, over the decades I've done a few warm (hot) drain oil changes on engines, gearboxes and rear diffs and despite not being mechanical and a bit clumsy I've never had any trouble with the oil being warm (hot) - other than some always missing the bowl(s) and going on the ground, we don't all have lifts or pits or even any sort of shelter from the elements when it's too hot, too cold, too wet too windy, oh, the joys. ☹️ Farting about with cars is always a dirty, messy business, particularly petrol and worse still diesel engines but you do what you can to avoid oil, grease, rubber, dust, dirt and debris as much as you can getting on you and your clothes. Professionals are often more interested in speed of the job, and getting on to the next job, than taking time, being thorough (and giving a **** for many of them in my experience). Professional just means you're doing it as paid work not necessarily that you are any good at the job. I only started doing work on my cars because I was fed up or sorting and redoing properly work I'd already paid professionals to do, often I would do a better job not because I was better but because I cared about the quality of the work and outcome and didn't give myself time pressures. Is it worth worrying about any sort of real longevity on a 2023 car to make it worthwhile to worry about a bit of extra effort with the engine oil and just go with what many (most?) others do and just meet the minimum requirements for warranty then get the least expensive oil for whenever you feel the need for an engine oil change.
