I gotta say, I love my macbooks. Every Apple laptop I've owned that has USB-C ports will happily charge itself from a 5V/1.5A wall charger (albeit extremely slowly).
That hasn’t been my experience. I once tried to charge an M3 MBP via a lower powered wall plug. It was left off over night and the following morning the battery was still at 1%.

Theoretically yes, practically that hasn't been built yet. I've only seen it for 2.5Gbase-T, and only for 802.3bt Type 3 (51W). If anyone's aware of something better, I'd be interested too :) (Then again I wouldn't voluntarily use 5Gb-T or 10Gb-T anyway, and ≈50W is enough for most use cases.)

Eh. A lot of laptops won't accept less than 60w My work laptop won't accept less than 90w (A modern HP, i7 155h with a random low end GPU) At first everyone at the office just assumed that the USB C wasn't able to charge the pc

Some devices expect USB-A on the charger side instead of C
USB-A pump out 1A5V(5W) regardless of what's connected to it, then it negotiate higher power if available.
USB C-C does not give any power if the receiving device is not able to negotiate it
FWIW I got a Xikestor 10G adapter with the Realtek chipset from AliExpress and it underperforms my much cheaper 5G one.

Laptop charges fine regular 5V as well.
I have a RTL8157 5 Gbps adapter from CableMatters. Interestingly it seems to get burning hot on the MacBook M1 Pro while it remains cool on the M5 Pro model. Maybe the workload is different, but I would not rule out some sort of hardware or driver difference. I only use a 1G port on my router at the moment.

Low-cost devices are exactly where 10/100 is still widely used. On PCs, it's a common power-saving mode.
For those of us who don’t know, how does it save power vs a 1gbe running at low throughput?
A Framework expansion card was also announced this week. https://frame.work/nl/en/products/wisdpi-10g-ethernet-expans...
That link notes: "Card supports 10Gbit/s and 10/100/1000/2500/5000/10000Mbit/s Ethernet" Nice to see; some NICs are shedding 10/100 support. Apparently, it's not necessary to do this, even in a low cost device.

However — unlike copper twisted pair — the bandwidth current fiber media can carry is nearly limited by nothing but the optics at each end.
That doesn't solve the chicken and egg problem. What probably would is something like having PCIe and USB to 1Gbps fiber adapters that cost $5.
I suspect the combination of the absence of cheap-o all-in-one AP/router combo boxes with any SFP+ cages and fiber cabling's reputation of being extremely fragile have much more to do with its scarcity at the extremely low end of networking gear than anything else.
[0] This is a two-port SFP+ PCI Express card
Is it also possible to power a laptop through those adapters? PoE++ can deliver up to 100W of power, more than enough for most laptops.
Surely a matter of time until someone does this…
