I've been playing RPGs since middle-school and original D&D & original Traveler, which should tell you, I'm not a young-un.
I am male and married with adult children. I am LGBTQ+ friendly with family members and friends who are LGBT. I don't allow politics or culture wars at the table.
As a GM, I've evolved over the decades going through a silly high school phase, an overly serious college phase, a "realistic fantasy world phase", to settle on an it's-a-game-let's-have-fun phase. Everyone has lots of entertainment options. I strive for a virtual table where this entertainment option meets your RPG itch and is fun enough to justify your time.
This means that while there will be a premise to the campaign, which will vary depending on the particular campaign option selected, there won't be a plot. I have ideas of characters and plot-hooks, and depending on the particular premise, it may include a premise I'd like to see resolved but how it is resolved is up to the player.
NPCs will have strong motivations but whether they turn out to be a friend or foe, villain or ally, will be up to the players. Of course, some might be very hard to "flip" to ally but it won't be impossible for any of them. Similarly, there may be some that seem natural allies who might not be what they seem. Maybe they have their own agendas that do not align with the party, or are alienated by the actions of the party.
It's up to you the player.
I hate a railroad as a player and as a GM. This does mean, I expect the players to pay enough attention to the campaign to help suggest next steps, and this is in fact the main thing I am looking for in new players: you need to understand what has happened in the campaign so far, and this means paying attention in game, remembering what has transpired, and join party discussions on what you want to do next. This will mean some amount of out of game time in discussion and either a good memory or good notes.
It doesn't mean you need to be a closet-actor or an extrovert. We'll make space for quiet players. Engagement is what matters.
I've been running Pathfinder 2E for about 4 years now so I am very familiar with it.
