as others have metnioned: try the trackpad, before dismissing it.
i only need a mouse to edit photos.
My music production tools (aka) Digital Audio Workstation is also slightly better using a mouse, but i can still work pretty nicely with just the trackpad (+ of course a lot of keyboard commands)
otherwise: (Mac) trackpad for life! 💕
(it's not that the Mac trackpad hardware is actually that much more advanced, they "just" made the software gesture recognition work so great, despite the theoretical lack of precision of trackpad hardware)
before i switched to Mac, i also thought that i'd need a numerical keyboard, as i previously had many keyboard shortcuts customized to utilize it on my DAW when i was using Windows laptops with num pads
so i also bought a Bluetooth num pad add-on before my MBP arrived, just to realize later on that i actually never use it, as my new custom KB shortcuts are even better than my previous ones.
Never missed it for a second, though of course there are some other use cases where such a device can indeed make your life a lot easier.
