We all know the Sony a1 + Sony FE 600 F4 is king of BIF/wildlife solutions, but when it comes to the longest-zoom mirrorless setup, we have:
Sony, affordable (without a pro lens)
- Maximum focal length (when cropped to 20MP) for full-frame solutions: Sony a7R IV + Sony FE 200-600 at sqrt(61/20)*600=1048mm
- Maximum focal length (when cropped to 20MP) for APS-C solutions: Sony a6600 + Sony FE 200-600 at sqrt(24/20)*1.5*600=986mm
Sony, premium (with a pro lens and 2x teleconverter)
- Sony a7R IV + Sony FE 600 F4 + 2x TC at sqrt(61/20)*600*2=2096mm
Canon, affordable (without a pro lens)
- Maximum focal length (when cropped to 20MP) for full-frame solutions: Canon R5 + Canon RF 800 F11 at sqrt(45/20)*800=1200mm
- Maximum focal length (when cropped to 20MP) for APS-C solutions: Canon R7 + Canon RF 800 F11 at sqrt(33/20)*1.6*800=1644mm
Canon, premium (with a pro lens and 2x teleconverter)
- Canon R7 + Canon RF 1200 + 2x TC at sqrt(33/20)*1.6*1200*2=4933mm
Nikon, affordable (without a pro lens)
- Maximum focal length (when cropped to 20MP) for full-frame solutions: Nikon Z9 + Nikon Z 100-400 at sqrt(46/20)*400=607mm
- Maximum focal length (when cropped to 20MP) for APS-C solutions: Nikon Z fc + Nikon Z 100-400 at sqrt(21/20)*1.5*400=615mm
Nikon, premium (with a pro lens and 2x teleconverter)
- Nikon Z fc + Nikon Z 800 + 2x TC at sqrt(21/20)*1.5*800*2=2459mm

Conclusions
- If you can afford a pro lens, the mirrorless setup with the maximum focal length is: Canon R7 + Canon RF 1200 + 2x TC at sqrt(33/20)*1.6*1200*2=4933mm
- If you can't: Canon R7 + Canon RF 800 F11 at sqrt(33/20)*1.6*800=1644mm
