Hi,

a.. What are the various options to program the MCU other than the JTAG Interface.

Other the JTAG you can program the MCU through various communication ports such as UART, SPI, I2C, CAN, and USB. You can use either the ROM-based bootloader or the flash-based bootloader. Please refer to the Bootloader user's guide. https://www.ti.com/lit/pdf/spmu301

b.. Please confirm on the USB interface for programming the MCU

Yes, as answered above, you can use USB in DFU mode to program the MCU. 

Refer to the flash-based USB DFU bootloader example in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c123gxl\boot_usb

Refer to the flash-based UART bootloader example in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c123gxl\boot_serial

c.. Which UART will be the default UART for the MCU.

If you are using the ROM bootloader, then only UART0 can be used for bootloading. If flash-based bootloader, you can configure any one of the UART ports for bootloading.

We don't normally review customer's schematic but quickly glancing your schematic I don't really spot anything wrong. Please refer to https://www.ti.com/lit/pdf/spma059 system design guideline for TM4C123 for best practices.
