10GBASE-LRM and EDC: Enabling 10GB Deployment in the Enterprise

... I'm beginning to re-think my choice of SFP modules. Because this is a home lab cost and distance are major consideration. The limitation is the SG300-20 and available SFP modules which can be summarized as:
MGBBX1 | 1000BASE-BX-20U SFP transceiver, for single-mode fiber, 1310 nm wavelength, support up to 40 km |
MGBLH1 | 1000BASE-LH SFP transceiver, for single-mode fiber, 1310 nm wavelength, support up to 40 km |
MGBLX1 | 1000BASE-LX SFP transceiver, for single-mode fiber, 1310 nm wavelength, support up to 10 km |
MGBSX1 | 1000BASE-SX SFP transceiver, for multimode fiber, 850 nm wavelength, support up to 550 m |
(https://www.cisco.com/c/en/us/products/collateral/switches/small-business-smart-switches/data_sheet_c78-610061.html)
(Q1) I made the assumption that shorter maximum distance meant lower cost for both SFP modules and cabling. Is this correct in the case of SFP + cabling for the SG300?
(Q2) Will a MGBSX1 and SFP-10G-SR (https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/data_sheet_c78-455693.html) work together?
(Q3) If the answer to Q2 is yes, is OM3 or OM4 my best choice for re-usability in 10G and lower cost?
(Q4) If the answer to Q2 is no, what do you recommend?
