I expect you are aware of the big differences in dynamic range with electronic vs mechanical shutter on A7V. If I had this camera, I might have elected to use the electronic first-curtain (EFC) shutter for all portrait and landscape photography in the 100-800 ISO range.
No, I'm not aware of it. Actually I wanted to avoid the electronic shutter unless I do sports or running dogs. But it seems that I should rethink my calculation?

My point was about avoiding full-electronic shutter in the 100-800ISO range. The dynamic range of the camera is considerably better (even approaching the dynamic range of the large/medium format cameras at ISO 100) when using mechanical or EFC shutter.
Between the full mechanical and electronic first-curtain shutters, the latter allows to avoid the shutter shock that can negatively affect the resolution (sharpness) of the photos.
From ISO 1000 and higher, the dynamic range is practically the same with ES, MS, or EFC shutter; thus, the choice should be decided by considerations other than the camera dynamic range.
There are different ways of dealing with the choices. My own is to save the custom sets to 1 - 2 - 3 on the PASM dial.
I've got the A7V. I shoot mainly portraiture and some sports (outdoor tennis and indoor volleyball). For portraits I've got the EFC shutter turned on. I'll shoot some ES for subject coming straight at me or twirling around. The challenge for me with tennis using ES is two fold: .1 Can the dynamic range good enough to handle a dark skinned player wearing white or vice versa? and 2. Will there be effects of rolling shutter i.e. elongated racquets and or oblong balls? I'm quite bullish on both. On no. 2 I tried ES with my R6MKII on a tennis teaching pro and I didn't see any distortions. However, I shot only at 1/1000 shutter speed---for WTA/ATP players I got be at least 1/1600 shutter speed or preferably at 1/2000---those gals/guys hit pretty hard.

I just ran some tests yesterday and learned firsthand the difference. I shoot all my photo cameras in mechanical shutter, but I wanted to test the 30fps/silent mode. I shot some high contrast scenes around sunset and was pretty surprised that I could not recover some highlights in Lightroom. I’ve become so used to being able to basically recover anything in raw that I was actually surprised by this. I’ll test the efc today as I expect it to be much better considering how well the dynamic range tests for this camera have performed.

Oh gosh, that bad?
Could you post some 100% screenshots difference with and without ES? I would have thought 1 stop difference is what we have nowadays with the current cameras.
It’s not bad at all. It’s literally that 1 stop of highlights you may be able to recover that I missed there. I shot now in full mechanical shutter now and confirmed that yes, I was able to pull down and recover everything that looked clipped in the jpeg. Also I brought up shadows a pretty insane amount. I definitely believe these DR tests.

I dont beleive any testing is correct. take your a7v and shoot the same image 16 stops apart and try and recover the image.
There's one small thing that sounds a bit unexpected. A high/better dynamic range shouldn't affect the highlights when the camera metering is right. The added dynamic range is all(!) about better shadow recovery and has nothingto do with the highlights. When the highlights are clipped, this is caused only by the metering that gave the exposure shifted to the right, either due to a camera metering decision, or due to the photographer' choice.

Understood.
Seems then that there's no confusion on the sensor capabilities.
It is also evidenced by preview:
"To start, this may be one of the most ISO invariant cameras we've seen to date when shooting with the standard, mechanical shutter mode.....In our tests, we saw essentially no shadow cost to an image shot at ISO 400, brightened to match an image shot at ISO 6400 with the same exposure settings." https://www.dpreview.com/articles/1731357282/sony-a7-v-dynamic-range-test-studio-scene
