Should I change the oil in my new car after 1000 miles?

I have a new Lexus LBX that has now done 1200 miles. The oil change interval is the standard 10,000 miles or 12 months. I've read that some would suggest changing the oil and filter now that it's done...

I only do 3000 miles a year - do I need to service my car annually?

I have a 2016 Ford Focus and its MoT is due end March. Its only done 3000 miles since its last MoT and service. Should I get it serviced or could I get away with just an MoT this time?
