10GBASE-T works with regular RJ45 connectors when paired with cat6a+ cabling, but it’s capped at 10G over 100 meters. A switch that supports 10GBASE-T is necessary, since there aren’t standard SFP+ or QSFP faceplates available, and the enterprise market doesn’t require them.
You have two choices using a typical wall plate: an LC fiber coupler or an MTP/MPO coupler such as this link: https://www.pimfg.com/product-detail/SPM-MPO-WH. You can connect either a QSFP BiDi optic with standard OM4 LC-LC cable or a QSFP MM/SM optic using MTP/MPO cables.
