Long Macro Zoom?

One of my favourite photographic subjects is nature close-up; buds in spring, flowers in summer, leaves in autumn. I've used a lot of different A-mount lenses for that over the years, APS-C and FF, macro and zoom, and many of them have done a good job. I can still use them on the LA-EA4 with my A7Rii but I am thinking about getting a dedicated FF E-mount zoom for the purpose.
It would need to cover at least 70-150mm to be useful, it doesn't need to be a true macro lens as the Rii has plenty of crop capability, but it does need a short MFD and it needs to be sharp there, which in my experience most aren't (and paradoxically the cheaper APS-C lenses are often a lot better in that than the expensive FF lenses ...).

I'd also be wanting to use it for the occasional portrait and so on so a constant f2.8 would be useful. Can anyone recommend something that will do the job?
Or shall I just stay with the A-mount macros and crop as I need?
