I want to download a BED file of various genome annotations (introns, exons, 3' UTR, 5' UTR) for a given assembly. I can do this through the UCSC table browser following these instructions, however I'd like to do it programmatically. Currently I get these regions from the full refGene table using MySQL to download the table and a custom script to parse out the regions into BED format. Does UCSC already offer an established way to do this?

Yes , you can access the mysql server using a simple sql script:

$ echo -e "chr1\t10000\t20000\nchr1\t30000\t40000" |\
awk -F '\t' '{printf("select \"%s\",\"%s\",\"%s\", G.name,G.txStart,G.txEnd from refGene as G  where chrom=\"%s\" and not(%s>txEnd or %s<txStart);\n",$1,$2,$3,$1,$2,$3);}' |\
mysql --user=genome --host=genome-mysql.cse.ucsc.edu  -A  -N -D hg38

I also remember Heng Li wrote a tool to batch-query the UCSC: https://github.com/lh3/misc/blob/master/biodb/batchUCSC.pl
