Best sources for free LIDAR point clouds (probably LAS or LAZ format):
US Interagency Elevation Inventory: https://coast.noaa.gov/inventory/
For MICRODEM, the data must be in UTM or geographic coordinates. There are options to reproject with MICRODEM, liblas, or lastools.

Getting lots of data
|Some surveys may penetrate water; others only coastal strips of land. For many areas several dates are available, showing temporal change.|
The National Map has two advantages over Earth Explorer
|USGS Earth Explorer||http://earthexplorer.usgs.gov/||
see coverage on selection map, click on rightmost button in the data set
listing. Recommend downloading a KML outline, opening in Google
Earth, and downloading from there. These do not come
with projection information in the file, so get the metatdata. At
least some are UTM, while others are state plane.
Importing the region desired from a KML or shapefile can be helpful. You must have logged in for these to work.
Must be logged in to see the bulk download option.
Must add results to bulk download one screen (10 files) at a time, using the checkbox under Result Controls.
Then view cart, checkout, and wait for email to start bulk download (which might have institutional permission issues, and should be done at home).
There appears to be a limit of 100 files; you might have to create multiple orders. You should be parsimonious is what you select, as even 100 tiles can be a 25 GB download. In addition, the 100 files you set will have an interesting spatial pattern, making it hard to fill in the holes later.
