Another A6700 vs A7CR choice

I am a hobbyist, started with 35mm film over 50 years ago. Have progressed through many digital cameras, but here is what I have today (I have kept my first film camera kit, which is in excellent condition). I went with APSC to minimize weight/bulk as I travel frequently. Only interested in photos, not video. Mainly family photos, travel photos, bird photos.

APSC

·        A6500

·        Sony E 11mm f/1.8 (for wide interiors, e.g. churches)

·        Sony PZ 16-50 F3.5-5.6 (hardly use)

·        Sony 18-135 OSS F3.5-5.6 (use this one all the time)

·        Sony 70-350 G OSS F4.5-6.3 (wildlife photography)

FF (Vintage glass, manual focus, autoexposure)

·        Honeywell Pentax ES (film)

·        SMC Takumar 28mm/F3.5

·        SMC Takumar 85mm/F1.8

·        SMC Takumar 50mm/F1.4

·        SMC Takumar 55mm/F1.8 Macro 1:1 (some great flower pix)

·        SMC Takumar 135mm/F3.5

I am looking to upgrade my A6500 with either the A6700 or A7CR.

I have used my vintage glass with my A6500 with a M45 adapter to good result.

Based on other threads, it looks like I can use all my lenses with the either camera, but don't get the full comparative advantage of the A7CR when using APSC lenses.

Other than the major price difference between the A6700 and A7CR, what should I consider in making the choice?
