Thanks to the help of some threads/posts on this awesome forum, u/Human_Spirit on Reddit, among others who helped me out, I've successfully upgraded my E6330 to Mojave 10.14.4.
Machine Specs:
Latitude E6330 BIOS A11
Core i5 3320M
Intel HD 4000
Clover R4920
Broadcom BCM94352HMB WiFi 867Mbps + BT 4.0 Card
WD Blue 250GB SSD
macOS Mojave 10.14.4
Working: WiFi, Bluetooth, iMessage/App Store, APFS, Keyboard, Trackpad, Backlight Control, Audio, HDMI, HWMonitor, Battery Indicator, Turbo Boost, Hardware Acceleration
Issues: Touchpad (Alps V3) seems to be recognized as both a mouse and a trackpad. As such, it's impossible to use natural scrolling for the touchpad and reversed scrolling for a mouse (so the mouse functions the same as it does in Windows). If you reverse the mouse in preferences, it also reverses the scroll direction in the trackpad preferences.
My EFI contents are attached. Decompress with 7 Zip.
