Pentastar and HEMI are still port injected.We need to make a list of non-DI cars left
Hyundai recently switched back to port injection on some of their cars
The lame-duck Spark is still port
Honda's own HR-V still uses a non-DI (SOHC) R18
Most of Nissan's cars are still port injection too (they still make the Maxima with the VQ35DE)
Toyota uses dual injection which reduces the DI problems

We have 2 2020 CRV'S, my wife's with 2300 miles, operated much as yours short trips, grocery getting, etc, with occasional highway miles, on Mobil1 0W-20 EP her Blackstone report showed similar thinning out-of-grade and had 3.5% dilution. Mine, with the same oil with much more highway miles after a 4300 mile OCI, was also thinned below grade and had 2.5% dilution. After a lot of advice here on the forum and discussions with my dealer's service manager and my Honda Master Certified Technician, have come to the conclusion, given the propensity of these engines to be very hard on oil, suggested a switch to a 0W-30 or 5W-30. I'll do another UOA after 3000 miles and see what it looks like. Most likely will use Mobil1 5W-30 EP as it rarely gets below zero here in Central Pennsylvania and it's easier to find than 0W-30. Obviously Honda's MM is an algorithm which, as far as oil life I'm going to ignore. With these 1.5t's, and using 0W-20, I don't believe a 5k OCI is, long term, going to be prudent as far as engine life. Incidentally, my MM was indicating 50% oil life remaining at 4300 miles with 2.5% dilution and thinned below grade. I'm hopeful that with the 5W-30 I can get back to 4-5k intervals. Sincerely believe there is no magical 0W-20, these engines need a 30 weight based oil unless you're not planning to keep your CRV for long or are willing to do OCI's at 2500 miles. I'm sure others will chime in on this, but I'm going to 5W-30.
I don't know if I would use VW as an example of success at anything...have you seen their reliability standings? But you are correct, I can spend my money where as see fit.
Save a few drops of gas, but reduce long term reliability and service life of the engine....makes complete sense from a carbon foot print standpoint. Because building engines and parts are carbon neutral so its ok to have shorter service life to save a few drops of gas.
Are you saying that the Honda dealer recommended 30 grade oil?
Have tried both Mobil1 0W-20 AFE and EP, with similar results in my (now with 20k)
Good list. Add Redline 0w20 with a KVM of 9.1. My brother has the same engine in his car and I'm going to suggest he switch.
No concern going with 30 weight? I'm surprised the dealer would recommend something outside of what Honda is recommending.
Also considering the Castrol Edge EP 5W-30 as well as the Mobil1 EP 5W-30 as they both carry the Honda HTO-06 approval. I'm currently running Mobil1 5W-20 EP and will do a UOA at 3K miles. I'm not expecting miracles.
He's on crack, no oil is going to have any sort if impact on the engine's tendency to dilute the oil with fuel, which is the result of programming and engine design. It's a low displacement engine that's difficult to get warm and is exclusively direct injected (no port injected low speed operation or warm-up). This makes it inherently more likely to be operating in a mode where excess fuel is used due to operating temperature (warm-up) and at engine speeds where DI is sub-optimal, which results in more of that fuel making its way onto the bores and down past the piston rings into the oil. DI operates best under high speed and load with an engine that's nice and hot. Port injection is superior at low load and low speed operation, providing a much more homogenous A/F mixture that doesn't wash down the walls. This is why many marques are now going with hybrid injection, which, while more complex, allows them to avoid the pitfalls of DI while also being able to exploit its strengths.
