A wonderful achievement for India - the entire nation came to a standstill during the lander descent, and the youtube live feed was the most watched in the history of that platform. These things are a big deal in the grander scheme of things around nation building.
Chandrayaan 3 benefited from the terrain mapping by the Chandrayaan 2 orbiter, that continues to troop on around the moon despite the loss of its lander 4 years ago. That detailed terrain mapping data is valuable to ISRO for future endeavors, in addition to enabling them to easily nail the Chandrayaan 3 landing.
One thing I wish would change faster is the use of frugal engineering. It's fine that the mission cost only $80 million whatever. But science and technology research should get quite a bit more money. ISRO in particular needs resources to build far more powerful launchers than the LVM3 which currently tops out at 10 tonnes to LEO / 4 tonnes to GTO.
