This is slightly tricky, because there are a number of varieties of smaller-scale football (soccer in the US) played in various parts of the world, and not all are the same.

It seems that Mexican "fútbol con bardas" or "fútbol de bardas" is the same game that they also call "fútbol rápido", and is essentially indoor soccer, that is, soccer played in a walled indoor space. The walls (bardas) mean that when the ball goes out of play it simply bounces back, so there are no throw-ins as in normal soccer, making for a faster, more continuous game. The playing surface is generally artificial turf in genuine indoor soccer. This is different from UK-style five-a-side football, which is played indoors by in a gymnasium or sports centre, in a walled arena but with a wooden or ceramic playing surface. (Besides, fútbol con bardas / fútbol rápido doesn't usually have five players per side, so the term is also unsuitable for that reason.)

So I think "indoor soccer" is the right game. The thing is, though, that in Mexico it's generally played in outdoor walled spaces, so calling it "indoor soccer" gives the wrong impression. So assuming this is for a US audience, I'd be inclined to use the common US term "arena soccer". The international term for the same game is "minifootball".

"Indoor soccer or arena soccer (known internationally either as minifootball, fast football, floorball specifically in the U.K.) is a game derived from association football adapted for play in a walled indoor arena. Indoor soccer, as it is most often known in the United States and Canada, was originally developed in these two countries as a way to play football during the winter months, when snow would make outdoor play difficult. In those countries, areas such as ice hockey courts or skating rinks are adapted for indoor soccer play. In other countries the game is played in either indoor or outdoor arenas surrounded by walls, and is referred to by different names (such as fast football (futbol rapido) in Mexico, showbol in South America, and indoor football (futbol indoor) in Spain).
Indoor soccer has different regulations from other versions of association football designed for indoor play, such as futsal and five-a-side football. Unlike futsal, which is played on ceramic surfaces, indoor soccer is played on synthetic turf. Indoor soccer courts are delimited by walls instead of lines, and there are no player throw-ins."

"Arena soccer" is a widely used term in the US. Here's Wikipedia again, whose first paragraph includes all three of the terms I've mentioned:

"The Major Arena Soccer League (MASL) is a North American indoor soccer league formerly known as the Professional Arena Soccer League. MASL is an affiliated member of the World Minifootball Federation (WMF), the governing body of the sport."

"Indoor soccer" would be correct; it's just that for Mexico, where the game is nearly always played outdoors, it seems kind of misleading to the uninitiated.
