Does any of the other Delivery modes other than DIRECT has any impact or use on Topic subscription?
Does any of the other Delivery modes (PERSISTENT or NON-PERSISTENT) other than DIRECT has any impact or use on Topic subscription? Also in the Solace UI, when publishing a Topic there is an option to switch the Delivery mode, but didn't see this has any impact on consumer/Subscriber side. I have seen this has an impact on Queue subscription only.

I am not sure what you mean by "impact" in the above description. Topics are fundamental to the Pub-Sub messaging pattern. The mode of delivery determines how the message is handled in the broker. More on that here. One of the characteristics is whether a message is acknowledged or not. A good source of this info is here and there is a very good video near the bottom with Aaron Lee walking you through Topics.
Solace generally recommends publishing on a Topic, even with Guaranteed/Persistent messaging. You would add a subscription(s) to Queues to allow these messages to be persisted.
So a Topic itself is not "impacted" directly by the Delivery Mode per se. What IS impacted is the handling of the message once its Topic has been determined at the broker.
