Most common oven temperatures:

325°F/160°C, 350°F/175°C, 375°F/190°C, 400°F/205°C, 425°F/220°C

So functional range of temps for most baking is 160-220°C with 175°C being the most common for most standard dinner recipes. Every non-commercial oven I’ve ever used defaults to 350/175 unless you set it otherwise, and I’ve used a lot of ovens. Commercial ovens are a bit different, most don’t have a default or if they do they have memory built in to default to your last temp used, but in my experience the most common temp for commercial baking is more often 375/190.

Though obviously individual recipes vary, that’s just averages across the many recipes I’ve made in both home kitchens and commercial kitchens. I’ve used 425/220 many, many times, as have I used 325/160 many, many times. I’ve also used outside that range but it’s far rarer. That’s mostly for specialized techniques or a very specific ingredient, or slow cooking and broiling obviously.
