you have really good collection of lenses. I'm happy that the L lenses still can be used on RF cameras, in case if I'm buying an RF camera I can use my L lenses without buying new RF lenses which are very expensive. I still use my EF lenses on my M50 with an adapter which I'm happy as well.As kzurro says, RF is the new EF - lenses for Mirrorless bodies and they do regular and L series too.
Quality of RF is better - as there's no mirror in the way the rear element sits much closer to the sensor, shortening the light path and can be placed exactly where the best image quality is achieved for that particular lens design, 2mm or 2 inches from the sensor.
Rear element is also larger so less edge distortion and what distortion there is (the 24-105 STM is pretty bad) is more easily corrected with the in-body processing. I think Lightroom has a profile for that lens too and they'll catch up for others that need it soon for those who only shoot RAW
The 100MacroL gives 1.4x mag and has a 'Bokeh control' ring to adjust the out of focus 'feel' and AF on Mirrorless is faster and more accurate, the focusing is done on the image sensor rather than separate AF sensors so no 'front or back' focus issues or need to micro-adjust / calibrate.
That said it'll be a while before DSLR is dead, there's no crop body (probably be the R7 when it eventually arrives) and there's no cheap camera for the masses or kit lens - if you're happy with the camera you've got and want a 24-70 then just get it and enjoy it, and you'll get a good trade in price for it a few years from now when you go mirrorless

I don't have many, taking in consideration that all them I purchased brand new.
(don't trust second hand equipment, even if they are more affordable)
