Need cabling advice to connect C3750G48TS and SG300-20 using SFP (home lab)

[aenagy]

I have:

(1) 2 x C3750G48TS

(2) 1 x SG300-20

(3) everything contained in a standard 19 inch rack, therefore the maximum cable distance would be no more than 3m (10 ft).

I need to connect these together. While I could use Cat 5/6 copper I would like to use the SFP interfaces just to dip my toe into the water. I will be adding more network gear at a later time to leverage the 10 Gpbs NICs (Dell/Broadcomm dual port 10G) in my servers. I mention this in case it might be better in the long run to focus on 10 Gpbs cabling.

Based on the research so far it kinda looks like I need:

(1) 2 x Cisco GLC-T (https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/gigabit-ethernet-gbic-sfp-modules/datasheet-c78-366584.html)

(2) 2 x Cisco/Linksys MGBSX1 (https://www.cisco.com/c/en/us/products/collateral/switches/small-business-smart-switches/data_sheet_c78-610061.html and https://community.cisco.com/t5/small-business-switches/fiber-link-between-sg300-and-catalyst-3750-fiber-switch/td-p/2618306)

(3) 2 x OM3 or OM4 cable (https://community.cisco.com/t5/other-network-architecture/50-125-om3-fiber-with-mgbsx1/td-p/2516214?dtid=osscdc000283)

Do I have this right?

You are correct direction, look at the SFP compatable matrix also for reference :

https://tmgmatrix.cisco.com/

if you looking 10 GB SFP you need to 10GB which can support 1GB/10GB, so in the later days you can move to 10GB as per the requirement.(rather you invest in 1GB SFP now, later it will be usefull, if you have all requirement 10GB.)
