Which should i get

• ⁠Budget: $3300 including lens, if new from Best Buy, I can finance the camera which makes it easier, which is what I'm planning to do. • ⁠Country: USA • ⁠Condition: New preferred to finance it, but it used is better deal then sure • ⁠Type of Camera: Mirrorless • ⁠Intended use: Photography • ⁠If photography; what style: Mostly portraits for client work, I'd love if it's good at landscapes as I want to travel and have a camera with me • ⁠If video what style: not planned really • ⁠What features do you absolutely need: EVF, if possible weather sealing, stabilizing • ⁠Portability: Don't mind how big or small it is • ⁠Cameras you're considering: Sony a7iii, Fujifilm XT5, Sony a6600, Sony a6100 • ⁠Cameras you already have: Just a couple point of shoots and a Minolta X-700 • ⁠Notes: I want to fully get into photography to do portraits and landscapes when I travel. I also want to be set up in an ecosystem I enjoy off the bat so that I won't have to purchase new lenses if I decide I don't like the ecosystem later. I adore the style of Fujifilm but am unsure of its quality for portraits as many have said the AF isn't the best, especially in comparison to Sony. Also if there's any recommendations for lens as I'd just purchase the body with no kit lens so I can find a good lenses, preferably a zoom lens with a good range to start off.
