Yes, if you want to keep the car for long, change the oil within 7,500 miles or 12 months whichever comes first. Make sure to reset the Oil Change with Flexible setting after you changed the oil.
The only thing I’d be concerned is changing oil at “Tiresplus”. Mazda dealer should be better, but you still want to find out what kind of bulk oil they use.
IMO, the best way to change oil without DIY is you buy your own oil (preferred 0W-20 or 5W-30 SP / GF-6 full synthetic oil) and correct OEM oil filter and take them to a reputable indie for the oil change paying them only the labor (~$20). And make sure ask them to save empty oil bottles and oil filter box for you.
