I think you are overthinking it and you are selecting software that is overkill. Of course if your first park is 800 units and you will have a staff of 12, then your list is appropriate. My first park started with Excel, Google Voice, and an email account.
After Excel, we migrated to Buildium which is more modern and easier than Rent Manager. Managing vendors and tenants is easier in Buildium. For example, you can natively pay vendors through EFT, but you have to use a 3rd party in Rent Manager, and EFT is not automatic. We ultimately switched to Rent Manager because we had to restrict banking from certain people in a way that Buildium would not allow.
Any text or calling will work, but Buildium and Rent Manager have texting built in so this is not necessary. Unless you have more than one property an 100s of lots, you can use something as simple as Google Voice. If you have many employees on different extensions around the world, you can use 8x8 or RingCentral.
Website can be hosted by anybody - Wix, Wordpress, GoDaddy, Google, etc. In my opinion they are all the same.
Project management can be your native Apple Tasks if it is just you. Otherwise, you can use Monday, Asana, Google, Trello, ClickUp as they are all somewhat the same. Of course if you are running a larger corporate office, Monday, Asana, and ClickUp will have better enterprise-level control features.
CRM is not needed unless you have many potential tenants calling that you do cannot control them all. Even Rent Manager uses the Rent Manager for their internal software sales CRM.
Metron is good, but there are others. We started buying Next Century from Flows.
