Advice for planting a Meyer lemon tree

I'd love to plant a Meyer lemon tree in our yard this year. Does this spot along our east fence look like an appropriate place (red arrow)? There are ~15 feet between the blue circled trees (no idea what they are but they put out purple flowers).

Any suggestions as to where/when and what variety to purchase? Ive read that ideal planting time is in spring.

There is river rock lining the perimeter of the yard. Should I replace the rocks around the base of the tree after planting or avoid putting rocks around that area?

I'm also considering buying two other citrus trees to keep in pots in a more shaded area of the yard, suggestions for that are welcome as well!

I'm a complete novice to gardening so any advice is greatly appreciated!
