It's my understanding that the "E" marked cables have the chip inside. Others may not. My Raspberry Pi's are powered via a USB port. Micro USB or USB C, +5V. Same deal with my Pi Pico Micro controllers. I have to be very careful what cable i use and how I connect it. Not having any MAC hardware its not a big worry. I'm still mindful of it though. Once you let the magic blue smoke out its game over for that device.
I don't know about cables with the E marked. I will check tomorrow in google. If it is possible to avoid the chip inside that is good.
I use a regular HDMI cable with my Raspberry Pi 3B+. I use a Micro-HDMI to HDMI cable with my Raspberry Pi 4B. I also have a Micro-HDMI to HDMI adapter so I can use a regular HDMI cable but decided one cable is better than two. For the last year I have using both my Raspberry Pis headless so log onto them using the free VNC Viewer. That way I don't have to bother with a monitor and a video cable for them.
When I bought my first Pi I also bought a 21-inch LCD monitor with VGA, HDMI, and DVI connections. That way I can use it with any computer I have.
BTW, normally a Raspberry Pi boots from a MicroSD card. A year ago I learned new firmware allowed the Raspberry Pi 4B to boot from USB. I now use a 32GB SanDisk Ultra Fit USB flash drive to boot it. That works great. The Ultra Fit is a good flash drive to use for this because it is really short and won't fall out like a regular size flash drive might do.
Speaking of USB cables it was a lot simpler when you just had to contend with USB 2.0 or USB 3.0. Now you have all times of complications.:
USB 3.0 aka USB 3.1 Gen 1 aka USB 3.2 Gen 1
USB 3.1 aka USB 3.1 Gen 2 aka USB 3.2 Gen 2
USB 3.2 aka USB 3.2 Gen 2x2
USB 4 aka USB4 Gen 2x2 aka USB4 20 Gbps
USB 4 aka USB4 Gen 3x2 aka USB4 40 Gbps
Note even the connector type doesn't indicate speed. For example a USB A port could be faster than a USB C one. You can't tell by looking at them.
It is common for people to think all cell phone adapters are the same as a 5VDC power adapter. For example a Raspberry PI requires a stable 5VDC power supply whose output current depends upon the model. A cell phone or tablet adapter/charger does not put out a constant 5VDC but varies the voltage to charge faster.
That link doesn't work. How about this one...

The chip is what sets the voltage, depending on what the device needs / wants. It's what does the USB PD Power Negotiations. Without it all you get is the standard +5V. That's all I want or need, so no chip is fine for me. Most of my cables are A to C, and won't have the chip anyway. It's only the USC C to USB C etc that needs the chip.
Yes, Mike's been fiddling. This was the original thread

Yeah lol. These topics kind of grew of their own accord.
These should be up to date...

Yes only take +5v to avoid the chip, like external hdd/ssd or enclosures for external hdd/ssd I think they don't need more than +5v. It is to be hoped that later things will not change, that the devices and the usba cables planned for the +5v will not be obliged to have a chip inside.
