I am using STM32F103RF chip, in the startup folder I see a full list of startup_stm32f10x_??.s files, which one is suitable for my case?

It's an XL Density part, thus the XL startup would be the one to go with

STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\startup\arm\startup_stm32f10x_xl.s

Your projects also needs to define the architecture, either via a #define or command line -D

#define STM32F10X_XL /*!< STM32F10X_XL: STM32 XL-density devices */
