Cherry Tree? Peach Tree??

Cherry Tree? Peach Tree??

we want to plant a fruit tree in honor of our recently passed Corgi. he LOVED fruit. LOVED IT. we have a small space in front of the house that is a circle about 6 feet across. it currently holds some sort of flowering Japanese thing/tree that really is unattractive and pretty spindly. my questions are these: we are in Illinois, Zone 5? 6? (about 40 miles south of Chicago). i know that cherries and peaches do PHENOMENALLY WELL in Michigan, which is just a bit north of us. so i am not really worried about that. but which one would do better overall? our neighbor has a bi-color apple tree (one side red, the other green) and a pear tree that both do pretty well. the spot we have for whatever tree we plant has full sun for MOST of the day. then the giant mulberry tree about 25 feet away blocks the sun. is this a good spot for said fruit tree? if we do plant this tree this year, WHEN is the best time to do so? now? later when it has warmed up a bit? we would, of course, get a YOUNG tree and let it grow. or is it better to get a more mature tree? what is the normal way to put in a fruit tree and have it thrive? Thanks for any answers to my stupid questions!
