Sorry, I missed your last post, “I’m in the business” if only 
It is very difficult to find a unit that fits all requirements, but I would (and I Did) purchase the DrayTeK 130 modem and also purchase the ASUS RT-AC86U or the RT-AX88U and flash them with RMerlin firmware. (that is a must)
Note: RT-AC86U firmware is fairly mature where as the RT-AX88U is still young in terms of firmware but much more future proof (that choice you have to make for yourself) and of course budget is a consideration also 
AVM kit is very good/stable, but does have limitations and an ASUS router flashed with ASUSWRT-Merlin firmware is hard to equal 
In a completely sane world, madness is the only freedom (J.G.Ballard).
