OS Update Frequency - Corporate IT Support

Hey Ya'll, I'm looking to get some insight from those that use MacBooks in their company from an IT perspective. The place I work for recently purchased some new Macs and were planning to get them enrolled on a management solution but wanted to ask some basic questions. 1. In regards to updating the Mac OS, how often do you update the software or how long after a major OS release do you wait to push the update out to your devices. For example, for our Windows laptops, we generally keep our OS on the previous version. For example Windows 11 latest release is 24H2 but were currently running Windows 10 22H2 and when we do decide to move to Windows 11, we'll only roll out the 23H2 version so it gives Microsoft some time to work out any bugs on 24H2 before we roll that out. I went off on a bit of a tangent but in essence I wanted to get some idea on how other IT support teams handle updating their devices. I know Mac OS 15 Sequoia was released a few months ago in Sept 2024 and wondering if everyone has already moved over or if you're still running OS 14 in your company and if so, when do you think you'll push out the Sequoia update to your devices? 2. How do you determine when it's time to replace the hardware. Apple is well known for making devices and software that can be supported for 7 or 8 years or even longer but as usual, hardware can become slow over time. Do you have a 5 year period where you outright replace your devices regardless of performance or do you only replace a device when it starts becoming slow and laggy and when the battery performance starts to degrade? 3. Does anyone recommend any Mac management solutions. We've been looking into using Jamf, InTune, Kandji. Wondering if anyone had a good or bad things to say about either one?
