As for the flash you can get Godox V860 or TT600. You might also need a trigger and receiver. Godox sells those too. Just check one for you camera. Keep 8n mind that handheld flash may not be powerful enough for a large rooms. You would need a storage light for large rooms.
This one will likely outlive you unless you are rough with it. I've had mine for several years and have had no issues at all. I think it may be end-of-life though and not being made anymore: https://www.amazon.com/Manfrotto-Virtual-Reality-Aluminum-MPOLEVR/dp/B07BKRD7WR
