Your situation sounds like my previous residence. I found the following useful:
1. Good quality half sheet pans: they can be used not only for baking and roasting, but as an ad hoc prep work surface (on the stove top or elsewhere as "extra counter space")
2. A medium-sized straight rolling pin: my counter space was so small that a large rolling pin was unwieldy.
3. Half sheet Silpats: on top of their intended purpose, multiple silicone mats can be used on your prep surface, switching various ingredients off the minimal counter space if necessary
4. A set of Pyrex glass bowls with lids: they are not only versatile as mixing bowls, but they can also be used for storage. They stack well when unused.
I had a stand mixer but I don't believe it's truly necessary unless you can spare the counter space.
