Question I'm searching for the smallest DDR5 & PCIe 4 M.2 compatible motherboard ?

[93QSD5]

What I'm looking for​

I'm looking for the smallest possible motherboard that has the following features:

- Supports DDR5 DIMM modules
- Provides at minimum 1x PCIe 4 M.2 slot(s) for an NVMe SSD
- Provides minimum 1x SATA for HDDs.

GPU is irrelevant here, this system is purely focused on Size ≥ Storage > CPU > RAM > Power consumption
Budget should be under 100 bucks, might be open to buying used, but first new.

Ignore cooling & case concerns, I will take care of it.

What I have researched so far​

ASRock B760M Riptide Intel B760 So.1700 Dual Channel DDR5 mATX Retail (New):
- Costs almost 120 bucks, expensive cmp to rest
- Intel CPUs probably not cost effective here
+ Has 1x PCIe 4.0 x16 & 1x 2280
+ Has 4 SATA 6GB/s & 4 USB 3.2 Gen 1
+- Supports only up to DDR5-4800
+ Has more ports cmp to rest.
+ Has 4 DIMM slots
+ 2.5Gbps Net

ASRock Pro RS Intel B660M So. 1700 Dual Channel DDR mATX Bulk (Refurbished)
- Refurbished
+ Costs 80 bucks
+ Has 4 DIMM slots
- ONLY supports DDR4-3200
+ Provides 1x PCIe 3.0 x16 (x4) / 1x PCIe
4.0 x16
+ Provides 2x SATA 6GB/s & 4x M.2 2280
- Sadly only 1 Gbps
+ 4x USB 3.2 Gen 1

MSI Pro A620M-E AMD B620 So.AM5 Dual Channel DDR5 µATX Retail (New)
+ AM5 support, will be very cost effective
- Only 2 DIMM slots, not end of world but less than rest
+ Supports DDR5-4400, DDR5-4800, DDR5-5000, DDR5-5200 cmp to rest
+ 1x PCIe 4.0 x16 though only 1
+ 1x M.2 bis 2280 though only 1
- Sadly 1Gbps Net
+ Has 4x 6GB/s SATA slots
+ USB 3.2 Gen 1

What I think​

1. The Riptide one has 2.5Gbps Net, an extra PCIe 3x16 slot as well not 1, not 2, not 3 okay you get it, FOUR M.2 2280 slots, NICE.
But sadly 1) it's refurb 2) Only supports DDR4 3200.

2. The AM5 board supports AM5 CPUs (big plus) & high DDR5. It seems great to me but only has 1gbps Net and only 2 DIMM & only 1 Nvme slot.

This is where your expertise comes in. Did I miss something, does DDR5 really matter for my intented use case (storage handling (not NAS) and a bit of non-gpu data computing) ? More recommendations are great too.

Thanks in advance.
