If it is your intent to record your guitar playing, you need an *audio* interface with an "instrument" input jack, with or without MIDI.  The make and model is generally not significant.

You can consider several cost effective options here...

MIDI is a computer control language and does not transmit audio signals.  It is used for the control of electronic musical instruments and devices.

A guitar cannot be used as a MIDI controller usless it is connected to a guitar synth module or MIDI converter.
