Arista 7050SX3-48YC12 or 7050SX3-48YC8

I am looking for a pair of switches that can meet the following requirements:

SFP / SFP28 ports

- Looking to use those ports for 10Gb copper using sfp transceivers that let me plug in a copper cable.

- 25Gb using sfp28 (fiber).

- Good amount of uplink ports prefer 6-8.

I was looking at HPE FlexFabric 5950 48SFP28 8QSFP28 Switch, but I don't see any 10Gb copper transceivers. Just 1Gb and DAC available.

I saw Aruba has JL624A Aruba 8325-48Y8C 48 x 25Gb ports (SFP/+/28), 8 x 100Gb ports (QSFP+/28), but I am trying to avoid this unit because of how hard it is to get 3rd party transceivers. I know my company will not want to pay over 1k per transceiver.

There are 2 switches that Arista offer that can do that:

7050SX3-48YC12 or 7050SX3-48YC8. I don't have anyone that I trust to resell. If anyone has any vendors with the switches available?
