Get a Mac Mini with the M4 Chip and at least 24 gb ram ($1000 refurbished) - Intel Macs are phasing out and on the last leg of life. Use Logic Pro ($199) or start on Garageband (which is free with all Macs) and get a simple inexpensive Interface like a Behringer UMC204HD ($109 USD) or a Scarlett 2i2 Ver 3 used ($150 USD) - but basically stop wasting your time vacillating on what you think you should get - you get a Mac and you can do everything you want and more.
