Any toy/activity recommendations for an active 11 month baby?

My little boy started walking at 10 months. Now that he is 11 months and more stable, he loves to explore and gets fussy when we don't go out.

Little context. We live in Hawaii. We have taken him to the beach/pools/parks/indoor play space this past couple of months. We do this during weekends and mostly stay home during the weekdays because my husband and I work full time. We live in a high rise so we don't have a yard.

Any recommendations on home activities/toys he can enjoy during the weekdays inside our home? What keeps your little ones busy or what do you guys usually do to keep up with your active baby? I feel bad for not taking him out every day, but it's just tough after a long day of work.

Please be kind. I had a rough postpartum. Thank you.
