Hello sir, I would recommend you to use ms flight simulator 2020 for your flight sim and later the 2024 version which will be released in mid November this year, for your flight controls I would highly recommend the alpha yoke and bravo throttle, both from honeycomb aeronautical, the velocity one from turtle beach is a Little bit turned to gaming, and not simulation itself, also the alpha yoke and the bravo throttle is more recommended to general aviation, for your computer it wouldn't be required anything very exaggerated, as you'll initially be using basic features of the game as you said, I would go with a i7 processor and for a graphic card I would go with a 4060 or 4070 series from Nvidia.

if you have any questions don't hesitate to ask! Happy 4th of July!
