Canon camera and lens help please - EOS R7 and Full-Frame Lenses

So , currently have a canon point and shoot and now in the position to purchase a mirrorless camera and nice lens

I have got down to two camera

sony a6700 and canon R7

It has taken me a lot of reading and re-reading of stuff to get my head around the FF lens on the APS body.

I like the R7 but it only has four APS lens , the others are FF lens which I understand as below

so if I was using a APS on the sony , 50 mm it would be a 50mm field hitting the sensor but if I was using a 50 mm FF on the canon it would be the equivalent of 50 x 1.6 hitting the sensor the rest would be lost as it would be out with the sensor

Just wondering why canon havent invested in APS glass , I know there are going to be sigma lens this year 

if your going to be using FF lens, why not just get a FF camera or it is because of the extra reach you get 

If getting the canon R7 and using the FF lens , you would need to calculate what the lens actually will capture , something when picking up the sony aps with aps lens you wouldnt need to do

also, apart from what a FF lens on aps body is captured on the senson, I am still unsure what other things to take into account 

 

thanks

"When digital DSLRs were first released they were initially all APS-C size sensors ..."

Or APS-H and it doesn't explain why everything has to be dumbed down to the lowest common intelligence. It is still a stupid and not necessary theory, IMHO, as always.
