camera raw for sony alpha 7 and PS 5

HI

I am an amateur photographer and am very happy in my little PS5 world.  I do not want to commit to PS6 and the CC and a lifetime of fees.  I am, unfortunately, thinking about getting the sony alpha 7.  It is unclear to me if camera raw 6.7 will support it.  I have read 2 different answers on the internet

I love camera raw in PS. If I can't open these images in PS, can I do it in lightroom?  Does lightroom have a nice camera raw?  (I am using camera raw 6.3 and it is wonderful.)

Is there any easy answer for a very casual photographer who cannot justify the cost of monthly program fees?

thanks!
