My DS (ASD) had some of signs.
He walked late (18 months), stopped pointing when had previously, too easy / self sufficient. Collected objects (from 2.5)
But tbh he is young and as speech ok, some interaction / eye contact its not as you say very obvious. What you describe would not be considered a speech delay yet.
Looking at MCHAT yourself would be best
What happens if you interrupt his collection of items? Does he get cross?
Is there a to and fro e.g. if you sat him on your knee and did an action song would there be a back and forth of interaction between you? Does not have to be verbal could be a happy gurgle - but a you do something fun, he responds, you continue, he wants more - its the 2 way nature of interaction and the quality of interaction.
Does he look at your mouth when you talk rather than your eyes?
Does he do pretend play? Imitate e.g. head, shoulders, knees and toes type songs?
You can look at some websites like first signs or teachmetotalk which has a milestone list below:

THESE ARE THE FOLLOWING LANGUAGE MILESTONES THAT A CHILD SHOULD HAVE MASTERED BY THESE AGES FROM THE ARTICLE ON THIS SITE TITLED ?WHEN TO WORRY?
· Difficulty making and maintaining eye contact with an adult by 6 months
· No big smiles or other warm, joyful expressions during interaction with another person by 6 months
· No back-and-forth sharing of sounds, smiles, or other facial expressions by 9 months
· No babbling by 12 months
· No back-and-forth gestures, such as pointing, showing, reaching, or waving by 12 months
· No consistent responding to their names by 12 months
· No words by 16 months
· No following simple and familiar directions by 18 months
· No two-word meaningful phrases without imitating or repeating & says at least 50 words by 24 months
· No back-and-forth conversational turn-taking by 30 months
· Any loss of speech or babbling or social skills (like eye contact) at any age
The presence of any of these concerns warrants an immediate discussion with your pediatrician and insistence for a referral to an early intervention program and/or speech-language pathologist for a complete evaluation of your child?s communication skills.
Let me also add that babies who are doing well with development exceed these milestones by leaps and bounds. These are very, very low thresholds for all the skills listed. If your child is not meeting these basic guidelines, please don?t dismiss your feelings. There is in all likelihood a true developmental delay or disorder present. "
